5×8 Bathroom Remodel Cost Guide for 2025

Thinking about remodeling your small bathroom in 2025? Whether you’re looking to modernize a dated space or improve day-to-day usability, understanding the costs involved is key. On average, remodeling a 5×8 bathroom can cost anywhere from $8,000 to $15,000, depending on the materials, finishes, and labor involved. In this guide, we’ll break down everything you need to know about remodeling a 5×8 bathroom, including typical price ranges, labor costs, design tips, and how to get the most out of your investment.

What is a 5×8 Bathroom?

A 5×8 bathroom measures 40 square feet and is the most common bathroom size in U.S. homes. This is considered a full bath and features a sink, toilet, and either a bathtub or shower. The layout is especially popular as a guest bathroom, hallway bathroom or secondary bathroom. Due to its small footprint, homeowners are often able to splurge on higher-end finishes or customized touches, making it perfect for the budget-oriented homeowner.

How a Bathroom Remodel Can Add Value to Your Home

Remodeling a 5×8 bathroom can yield a strong return on investment—particularly because it improves both the home’s visual appeal and daily functionality. According to Remodeling Magazine’s 2023 Cost vs. Value Report, a midrange bathroom remodel recoups approximately 66% of its cost at resale, while an upscale remodel recoups around 36-40%. For homes with only one full bathroom, modernizing the space can also increase marketability and attract more buyers.

Beyond resale value, updating a bathroom provides lifestyle upgrades. Replacing outdated fixtures, old tile, or worn cabinetry not only improves aesthetics, but can also lead to better energy efficiency and water savings. New low-flow toilets, LED lighting, and water-efficient showerheads can help reduce monthly utility bills.

In a smaller bathroom, strategic design choices—like recessed storage, wall-mounted vanities, or bright lighting—can make a big visual impact. Plus, smaller spaces require fewer materials, which often allows homeowners to choose more premium finishes without a significant increase in budget. Whether you’re prepping for a sale or improving your forever home, remodeling a 5×8 bathroom can make a meaningful difference in how your space looks, feels, and functions.

Remodel vs. Renovation: What’s the Difference?

While “remodel” and “renovation” are often used interchangeably, they refer to different home improvement projects. A renovation focuses on updating or restoring existing elements without altering the room’s fundamental layout or function. For example, replacing the vanity, painting the walls, or updating tile would fall under renovation.

In contrast, a remodel involves altering the room’s structure or layout to change its purpose or improve functionality. Converting a tub to a walk-in shower, repositioning plumbing fixtures, or expanding the bathroom by knocking down a wall all fall under the remodel umbrella

Understanding the difference matters because remodels tend to be more complex, require permits, and have higher labor and material costs. Renovations are typically more cosmetic-oriented. Whichever you choose, you must set a goal so you have a clear idea of the overall scope of your project, which will create your budget and help you better understand your contractor requirements.

Factors That Affect the Cost of a 5×8 Bathroom Remodel

While the size of your bathroom is fixed, the total cost of your remodel can vary widely depending on several key factors. Here are some essential elements to consider:

• Material Quality and Finish Level
  Choosing high-end finishes like stone-resin sinks, marble tile, custom cabinetry, or designer fixtures can quickly push your budget over the limit. Consider more affordable options, such as ceramic tile or prefabricated vanities, to keep costs down without sacrificing style.
  
• Plumbing and Electrical Work
  If you’re relocating major components like the toilet, shower, or vanity, expect higher costs due to plumbing and wiring rerouting. Even minor electrical updates—like adding lighting or upgrading outlets—can add to your total.
  
• Labor Costs in Your Area
  Labor prices can vary significantly by region. For example, urban areas with a higher cost of living generally have higher contractor rates than rural areas.
  
• Permits and Code Compliance
  Many remodels require city or county permits, especially when making structural or plumbing changes. These costs can add up and also require extra time for approval and inspections.
  
• Structural or Water Damage Repairs
  Hidden issues like mold, rot, or outdated plumbing behind the walls can unexpectedly increase costs. These must be resolved before the remodel can proceed, which will add time and expense.
  
• Custom vs. Prefabricated Fixtures
  Custom-built showers, vanities, and cabinetry offer flexibility and a tailored look—but they’re pricier than standard, off-the-shelf options. Prefab fixtures are quicker to install and more budget-friendly.
  
• Scope of the Remodel (Cosmetic vs. Full Renovation)
  A cosmetic remodel may include paint, hardware updates, and a new vanity. A full renovation might involve gutting the space, upgrading plumbing and electrical systems, and installing entirely new fixtures.
  
• Project Timeline and Scheduling
  If you’re on a tight timeline, expedited work can increase labor costs. Conversely, scheduling delays or labor shortages may also inflate your total cost over time.

Key Cost Components in a 5×8 Bathroom Remodel

When planning your bathroom remodel, it helps to understand where your money is going. A 5×8 bathroom may be small, but the cost breakdown includes several essential components that contribute to the overall budget. From materials and fixtures to labor and installation, here’s a look at the main elements that drive remodel costs.

Toilet ($100–400)

A new toilet is one of the most essential upgrades in any bathroom remodel, and in a 5×8 space, choosing the right model is even more important. Compact or round-bowl toilets are ideal for smaller bathrooms, as they take up less floor space while still providing comfort. Basic models start around $100, while more efficient dual-flush or water-saving models and smart toilets may cost closer to $300–400+. Installation and disposal of the old toilet may be an additional expense unless bundled with a contractor’s services. Also consider your water bill as this is a hidden cost that you may not consider that will add up over time.

Ventilation & Exhaust Fans ($100–300)

Proper ventilation is critical in a 5×8 bathroom to prevent moisture buildup, mold, and long-term damage. A small space doesn’t require a heavy-duty fan—most homeowners can install an efficient unit for $100–300, depending on brand and features such as lighting or humidity sensors. If ductwork needs to be added or adjusted, labor costs could increase. Always check that the fan meets local code requirements for CFM (cubic feet per minute) based on bathroom size. Generally, it is advised to include as much ventilation as possible as moisture build up can wreck havoc to your bathroom.

Lighting Fixtures ($150–600)

Lighting in a small bathroom impacts both function and atmosphere. In a 5×8 layout, a single overhead light or a vanity light bar may be sufficient, keeping fixture costs relatively low. Homeowners can expect to spend $150–600 depending on design preferences—LED fixtures with dimmers or layered lighting setups can raise the price but also enhance ambiance. Since there’s less area to illuminate, you can often afford higher-quality finishes within budget.

Sink & Faucet ($200–500)

Sinks in small bathrooms should balance functionality with space efficiency. Pedestal sinks, wall-mounted sinks, or smaller vanities with integrated basins are popular in 5×8 layouts. Faucet choices will also affect cost—standard chrome fixtures are on the lower end of the range, while brushed nickel or matte black designer options can increase pricing. Combined, the sink and faucet typically cost $200–500, depending on material, style, and whether professional installation is needed.

Door or Entry Updates ($200–300)

Standard interior doors for small bathrooms usually cost between $200–300. In tighter layouts, pocket doors or sliding barn-style doors may be considered to improve flow. Material and finish choices (solid wood vs. hollow-core) will also impact pricing. Don’t forget to factor in labor if modifications to the door frame are required.

Window Replacement (if applicable) ($200–400)

Not all 5×8 bathrooms have windows, but for those that do, replacing an old, leaky, or outdated window with a modern, energy-efficient one can enhance natural light and improve ventilation. The cost typically ranges from $200–400, depending on window size, frame material, and whether privacy or tempered glass is used. Adding a window where none exists will significantly increase costs due to framing and siding work.

Shower/Tub Combo ($700–1,500)

A shower/tub combo is one of the most practical solutions for a 5×8 bathroom. Prefabricated one-piece or multi-piece surrounds are popular for their affordability, quick installation, and space efficiency. The cost ranges from $700–1,500 depending on materials (fiberglass, stone resin, acrylic, or solid surface), brand, and any additional features such as built-in shelving. This option maximizes both bathing and showering functionality in a tight footprint.

Bathtub Only ($1,000–2,500)

If your 5×8 bathroom will be used primarily for soaking, replacing a standard bathtub might be the right call. Freestanding tubs typically won’t fit, but alcove bathtubs are designed for small bathrooms and fit flush against three walls. Costs for tub-only replacements range from $1,000–2,500, including removal of the old tub and installation. Consider upgrading with tile surrounds or waterproof finishes to elevate the space.

Vanity ($250–1,500)

Narrow-profile vanities with drawers or open shelving are ideal for maintaining storage without crowding the space. Prices vary widely depending on the material (MDF, hardwood, composite), size, and whether the countertop and sink are included. Expect to spend $250–1,500, with installation and plumbing hookup often quoted separately unless part of a general remodel contract.

Labor Costs: Who You’ll Need for a 5×8 Bathroom Remodel

While smaller bathrooms generally require fewer labor hours compared to larger bathroom remodels, you’ll still need licensed professionals to ensure the job is done safely and up to code. Labor often makes up 40–60% of your total remodel cost, so knowing what each specialist does—and what they typically charge—can help you manage your budget effectively.

HVAC Technician ($75–150/hr)

HVAC technicians are multi-disciplinary and can handle almost all your needs, but they are significantly pricier than other contractors, so hire them only when necessary, such as for heating or gas work. Use other tradesmen before you call for an HVAC.

Electrician ($25–40/hr)

You’ll need a licensed electrician for any work involving wiring, installing outlets or GFCIs (ground fault circuit interrupters), vanity lights, and fans. It is critical that your wiring is up to safety and compliance codes for the safety of your household and those around you.

Painter ($70–100/hr)

A professional painter ensures clean lines, proper priming, and moisture-resistant finishes that DIY jobs often lack. You can reduce cost by handling prep work yourself—such as patching and taping—but keep in mind that painting in a high-humidity, tile-dense environment like a bathroom requires the right materials and techniques for long-lasting results.

Carpenter ($30–90/hr)

Carpenters may be brought in to install vanities, trim, or custom shelving—especially if your bathroom requires space-saving solutions. Since carpentry work is often quicker in a small room, labor hours are lower, but costs can climb depending on the complexity or customization level of the work requested and the availability of materials.

Plumber ($25–150/hr)

Plumbers are often the most essential—and most expensive—specialist in a bathroom remodel. Their tasks range from installing or relocating sinks and toilets to ensuring all fixtures are leak-free and compliant with local plumbing codes. In a 5×8 space, if you’re keeping the plumbing layout intact, costs stay manageable. But if you’re relocating fixtures, labor costs rise quickly. Emergency or after-hours plumbing work can push the higher end of the rate spectrum.

How Much Does a 5×8 Bathroom Remodel Cost?

The total cost to remodel a 5×8 bathroom typically ranges from $8,000 to $15,000, depending on material choices, fixture upgrades, labor rates, and whether you change the layout or keep existing plumbing in place. As homeowners consider remodeling projects, it’s vital to factor in additional costs such as permits and unexpected repairs that may arise during construction. For homeowners planning this project, it’s essential to establish a clear 5×7 bathroom remodel budget breakdown to avoid overspending. This breakdown should include costs for materials, labor, and any unexpected expenses that might arise during the renovation. Additionally, it’s wise to set aside a contingency fund of about 10-20% of your total budget to cover any unforeseen issues.

Here’s how that breaks down:

• Low-end remodels ($8,000–10,000) usually involve surface-level updates, such as replacing fixtures, repainting, and swapping in a new vanity or lighting.
  
• Mid-range remodels ($10,000–13,000) may include new tile, updated plumbing fixtures, a tub/shower combo, and minor layout improvements.
  
• High-end remodels ($13,000–15,000+) often involve custom cabinetry, designer fixtures, higher-end materials (like stone or porcelain tile), and more intensive labor or structural work.
  

Although 5×8 bathrooms are smaller than master bathrooms, they can still carry significant costs—especially in older homes where hidden issues like mold, water damage, or outdated plumbing and wiring are common.

By understanding labor needs and material costs upfront, homeowners can make informed decisions, avoid budget surprises, and create a stylish, functional space without overspending.

Tips to Maximize a 5×8 Bathroom Remodel

Remodeling a small bathroom may feel limiting, but with smart planning and design, a 5×8 space can become highly functional and visually appealing. Here are key strategies to take away from this guide:

Start With a Detailed Budget

Before any demolition or purchases begin, map out a detailed budget that accounts for materials, labor, permits, and a contingency for unexpected costs (typically 10–15%). Prioritize your must-haves—like a new shower or water-efficient toilet—and be flexible with finishes to stay on track.

Prioritize Smart Layout and Accessibility

In a compact bathroom, every inch matters. Consider future-proofing your space, even with simple updates like a wider doorway, a curbless shower, or blocking behind walls for grab bars-you’ll thank yourself later.

Use Light, Color, and Mirrors Strategically

Bright lighting and light-colored finishes can make a small bathroom feel more open. Add a large mirror above the sink or even a mirrored medicine cabinet to reflect light and create the illusion of more space. Recessed LED ceiling lights or under-cabinet lighting are great low-profile options that increase visibility without cluttering the room.

Take On Small DIY Tasks to Save Money

If you’re handy, handling minor parts of the remodel yourself—like demo, painting, or installing towel racks—can trim hundreds off your labor budget. Just be cautious with plumbing, electrical, or tiling, where DIY mistakes can cost more than hiring a pro. Start with safe, surface-level projects, and leave technical work to licensed contractors.

Choose Durable, Space-Saving Materials

Look for slim-profile vanities, wall-mounted sinks, or compact toilets specifically designed for small bathrooms. Waterproof luxury vinyl plank (LVP) flooring, porcelain tile, and moisture-resistant paint are durable and affordable options. When in doubt, go for high-quality finishes in high-traffic zones (floor, shower, sink) and save on decorative touches.

Avoid Moving Plumbing If Possible

Relocating plumbing fixtures like toilets or showers can drastically increase labor and permit costs. Try to work with your existing layout and upgrade fixtures in place. If layout changes are needed, combine them into one phase to limit the time and cost of rough-in plumbing.

Maximize Storage in Unused Spaces

Get creative with vertical and recessed storage. Built-in niches in the shower, floating shelves above the toilet, and mirrored medicine cabinets can all help minimize clutter without overwhelming the space. Consider pull-out drawers instead of deep cabinets—they offer better accessibility and help keep everything organized.

Remodeling a 5×8 bathroom or 5×10 is one of the most cost-effective ways to enhance your home’s beauty and functionality- just remember to plan accordingly. So whether you’re aiming for a quick refresh or a complete transformation, we hope we’ve given you the foundation to start your project with confidence.
