How Much Does a Wet Room Cost? [2026 Data]

In 2026, the national average cost for wet room installation is $13,000, with most homeowners spending between $6,000 and $20,000. Costs can range from as low as $5,000 to as high as $35,000, depending on the size of the space you're converting, the complexity of the plumbing, and the materials you choose.

Wet Room Cost by Room Size: How Much Space Affects Price

Installing a wet room costs an average of $225 per square foot, with a range of $175 to $600 per square foot, depending on the quality of materials and the scope of changes you want to make. Larger spaces will naturally push your total higher, so the square footage of the room you plan to convert is one of the most direct drivers of your final cost.

General Contractor Costs: What Homeowners Pay for Installation

A general contractor accounts for 10% to 20% of your total wet room project cost, which works out to roughly $1,200 to $4,000 for most installations. Hiring one lets you avoid the time-consuming process of vetting and coordinating individual specialists such as plumbers, electricians, tile workers, drywall installers, and painters.

Plumber Costs: What Homeowners Pay for Wet Room Work

Plumbers charge $45 to $200 per hour, and most homeowners pay an average of $1,500 for plumbing work on a wet room installation. That work typically covers rerouting plumbing lines, replacing fixtures, and installing the floor drainage system needed to properly waterproof the space.

Electrician Costs: What Homeowners Pay for Wet Room Work

Electricians charge $50 to $100 per hour, and the full scope of electrical work for a wet room runs $300 to $800. That budget generally covers replacing light fixtures, upgrading to GFCI outlets, and installing a vent fan to manage humidity in the space.

Additional Pros to Consider Hiring

Hiring a general contractor comes with the major benefit of being able to vet a single pro for your entire job. Otherwise, you'll need to find a few other specialists aside from plumbers and electricians to bring your project together.

• Drywall installer cost: $1 to $2.10 per sq. ft.

• Interior painter cost: $2 to $6 per sq. ft.

• Tile installer cost: $5 to $45 per sq. ft.

Wet Room Costs by Location: Where Labor Varies Most

Labor makes up 50% to 60% of a wet room project's total cost, and what you pay for that labor depends heavily on where you live. Professionals in high-cost-of-living states and cities charge more per hour, which is why wet room costs vary significantly across the country, as the table below shows:

Wet Room Cost Factors: What Determines the Price?

Several additional variables can shift your wet room budget significantly beyond the baseline square footage and labor costs, so understanding them helps you build a more accurate estimate.

Fixtures

At the affordable end, a pedestal sink runs about $200, a toilet around $200, and a standalone tub roughly $600 for materials, with installation bringing that combination to $2,000. Choosing high-quality or luxury fixtures can push that figure to $5,000 or more, and adding a standalone tub to the showering area adds $2,000 to $3,000 to your overall total regardless of tier.

Finishes

Finishes follow the same cost logic as fixtures: budget-friendly choices like glazed ceramic tile, stainless steel faucets, and standard lighting can keep finish costs as low as $1,000, while high-end materials can push that figure to $5,000 or more. 

Selecting premium options such as a marble floor, a custom type of tile for the walls, or custom copper plumbing fixtures can drive your overall project total up to $35,000. A local bathroom designer can help you balance your material choices against your budget to get the result you want.

Demolition and Prep

Converting an existing bathroom into a wet room requires professional demolition and prep before any build-back can begin, which typically costs $1,000 to $5,000, or an average of $3,500 for a standard-sized bathroom.

Permits

Wet room projects almost always require a building permit, which typically costs $150 to $1,000 depending on the size of the job and your local building department's fee schedule. Before work begins, confirm the exact permit cost with your contractor or building department so there are no surprises in your budget.

Why You Should Hire a Bathroom Designer

If you hire a bathroom designer near you, you’ll spend about 10% to 20% of the total project costs on labor. Designing a wet room is a complicated remodel that requires significant expertise in plumbing, ventilation, and waterproofing. A professional can help your project run smoothly and avoid costly mistakes along the way. 

Here’s why it’s ideal to hire a bathroom remodeling pro

Here’s why hiring a pro to complete your wet room is the best choice: 

• A pro understands how to properly slope the floor and install drainage so water doesn’t pool in one area, potentially flooding into adjacent rooms. Improper drainage can also lead to sewer gas leaks, posing a potential health and safety hazard.

• Simple waterproofing mistakes can lead to mold growth, leaks, and costly water damage.

• A bathroom remodeler ensures the job is completed safely and efficiently, meets code requirements, and passes inspections.

• A professionally installed wet room has a better resale value than a DIY wet room.

• Qualified pros understand the Americans with Disabilities (ADA) guidelines and can create a safe and accessible space for people with mobility issues and those who use a wheelchair. 

• DIY tile can look uneven, fall off the grout, or create a slip risk if you don’t use the right type or installation method.

• DIY plumbing or electrical work may void your homeowners insurance. Electrical work near water exposure in a bathroom is also a potential hazard. 

• Pros come with insurance and often offer warranties.

If you want to DIY a wet room installation

If you want to participate in the process, leave the heavy lifting to the pros and focus on smaller tasks:

• Prepping the space by removing towel bars, mirrors, surface-mounted shelving, etc.

• Protect nearby spaces by moving furniture and laying down plastic sheeting in your hallways

• Assisting with small demolition tasks, like removing old tile or caulk

• Selecting the fixtures, tile, finishes, and accessories ahead of time

• Locating your utilities and ensuring your contractor has easy access

• Assisting with cleanup after construction

• Installing accessories like mirrors and towel bars (as long as you don’t have to drill into newly-installed tile)

Wet Room Remodel vs. Renovate

When it comes time to install a wet room, you can choose between a remodel and a renovation. In all cases, a renovation will be the more affordable option, but it’s only possible if you already have a wet room and just want an aesthetic overhaul.

A renovation, which can include replacing plumbing fixtures, updating tiling, and installing new lighting fixtures, will cost an average of $12,000. Remodeling a bathroom to turn it into a wet room, which can include installing whole-room drainage, moving plumbing fixtures, and adding or relocating electrical fixtures, will cost $13,000, on average, and your costs can climb as high as $35,000.

How to Save Money on Wet Room Installation

Installing a wet room can cost tens of thousands of dollars, but there are some things you can do to keep remodeling and renovation costs to a minimum.

• Keep things as simple as possible: If you’re upgrading from a bathroom to a wet room, you’ll almost certainly need to rip up flooring to install drainage. However, you can keep costs down by avoiding expensive plumbing and electrical fixture relocation and maintaining the existing room’s size.

• Choose more affordable materials: Splurging on luxury materials can quickly drive your total from an average of $13,000 up to $35,000. Save money by skipping the marble tiling and copper plumbing fixtures and go for mid-tier finishes instead.

• Hire a bathroom remodeler: Hiring a professional to complete your bathroom remodel over DIYing will effectively double your project cost, but it also means a lower risk of water damage if you make a mistake, which can cost significantly more than you’d save DIYing. You’re also more likely to end up with a high-quality, professional appearance in your wet room.

• Consider doing some of the work yourself: You don’t have to leave all the work to a pro, though. Consider saving on some of the finish work that’s less risky to take on yourself, like installing wall tile, connecting plumbing fixtures, and installing trim and other finishes.

Does Installing a Wet Room Increase Home Value?

Installing a wet room will often increase home value, mostly because it involves a bathroom renovation. You can expect to see a 60% to 70% return on investment (ROI) on the project.

As far as the value of upgrading from a bathroom to a wet room, the added value will depend on your particular buyer. Some buyers see wet rooms as a luxury home feature and one that makes your bathroom look bigger, so they will gladly pay more for a house that includes one. Others may be indifferent or even dislike the idea of a wet room, so the project may not have any impact on home value. 

Pros and Cons of Adding a Wet Room 

Consider the benefits and disadvantages of installing a wet room before deciding whether it’s right for your home. 

The up-front costs of a wet room are often higher than a standard bathroom remodel, but many homeowners find that the luxury feel and increased home value that come with the investment are worth it.
