A wet room bathroom can be a fantastic option for those who want a stylish and low-maintenance space. These types of bathrooms are ideal for small spaces, as they don't require a separate shower enclosure.
The average cost of installing a wet room bathroom can range from £8,000 to £15,000, depending on the size and complexity of the design. This cost can be broken down into materials, labor, and any necessary plumbing or electrical work.
One of the main benefits of a wet room bathroom is its water efficiency. According to our article, a wet room bathroom can use up to 50% less water than a traditional shower and bathtub combination.
The water-saving benefits of a wet room bathroom can also lead to significant savings on your water bill.
Bathroom Conversion Costs
A wet room bathroom conversion can be a worthwhile investment, but it's essential to consider the costs involved. The initial installation cost can be higher than a traditional bathroom, but it can also lead to reduced maintenance costs and increased durability in the long run.
The cost of installing a wet room can vary depending on the size and complexity of the project, but on average, you can expect to pay between $11,000 to $18,000 (£8,000 to £13,000) for a medium-sized wet room.
Here's a breakdown of the average costs to install wet room components:
- Fittings: $800-$1,400 (£600-£1,000) for the tray and waterproofing, depending on size.
- Tiles: $70-$140 (£50-£100) per square meter for anti-slip tiles.
- Drainage and plumbing: $2,700-$4,000 (£2,000-£3,000) for tanking and plumbing.
- Labor: $700-$4,000 (£500-£3,000) for tiling, depending on the size of the room.
Keep in mind that these costs can vary depending on the size of the room and the level of finishes you choose. It's also worth considering the cost of extending underfloor heating to walls, which can add an extra layer of luxury and functionality to your wet room.
Cost Factors
Wet room installations can be costly due to the specialist nature of the work and the need for waterproofing and additional ventilation. Nick Cryer, founder of Berkeley Place, estimates a 20% to 30% uplift in cost compared to a traditional bathroom.
The cost of installing a wet room can range from $11,000 to $18,000, depending on the size and level of specification. Gemma Holsgrove, associate director at Sims Hilditch, suggests an even higher range of $20,000 to $40,000.
You'll need to factor in the cost of individual components, such as trays, tiles, drainage, and labor. Trays and waterproofing can range from $800 to $1,400, depending on the size.

Hidden Costs and Savings
Wet rooms can be a worthwhile investment, but it's essential to consider the potential hidden costs.

Careful planning and using qualified professionals can maximise the cost-saving potential of a wet room.
Another consideration is how you will heat and vent the space, as extending underfloor heating to walls can add to the overall cost.
Costs for this will vary, depending on whether you opt for electric underfloor heating or wet underfloor heating connected to the boiler.
The potential for reduced maintenance costs, increased durability, and potentially higher resale value can outweigh the higher initial installation cost.
However, these benefits are crucial for making a wet room a worthwhile investment, particularly for small bathroom ideas for a second bathroom or en suite.
The finished look of a wet room is always fantastic, but it's essential to consider the added costs and weigh them against the benefits.

Cost of Disability

The cost of disability can be a significant factor in planning a wet room. A disabled wet room can cost between £10,000 to £15,000, compared to £4,000 to £10,000 for a standard one.
This price difference is largely due to the additional features and considerations needed to create a safe and accessible environment for users with limited mobility. A disabled wet room typically prioritizes a larger floor area, allowing for easier manoeuvring of wheelchairs or walkers.
Strategically placed grab bars near the shower, toilet, and around the room provide additional support and balance for users. These bars need to be securely mounted to support a person’s weight, which can be a significant cost factor.
A fixed or fold-down shower seat is another essential feature, allowing users to rest safely while showering. This can be particularly important for those with limited stamina or balance.
Wider doorways and larger turning circles within the wet room are often incorporated to ensure wheelchairs can easily navigate the space. The type of flooring used in a disabled wet room is crucial, with a high slip resistance even when wet, minimizing the risk of falls.
The cost of accessibility upgrades can vary widely, but many homeowners spend between $100 and $18,000 (CAD 135 and CAD 24,325) on upgrades such as widening doorways or adding grab bars.
