Types of Wet Rooms and Variants

When it comes to installing a wet room, you have a few options based on the type of room and the features you want to include. Here are the most common types:

Open Plan Wet Room

  • With an open-plan layout, this style merges the wet room with other areas of the bathroom, such as a bath or toilet. This more extensive installation may cost between £5,500 and £8,000.

Labour Costs and Installation Time

Labour costs for wet room installations vary by location and complexity. Typically, you'll need at least two professionals to complete the job, which can include a plumber, tiler, and a specialist in waterproofing systems.

  • Labour Costs: £150 - £200 per day per contractor. A typical installation will take around 4 to 7 days, depending on the size and complexity of the room.
  • London and High-Cost Areas: Contractors in London or other high-cost regions may charge £30 - £100 more per day for their services.

Benefits and Drawbacks of Radiators in Wet Rooms

When designing your wet room, you’ll also need to consider the heating system, especially if you want to keep the space warm and comfortable year-round. There are two main types of radiators to consider:

1. Traditional Radiators

  • Pros:
  • Reliable and inexpensive to install.
  • Easy to replace or repair.
  • Cons:
  • Can take up valuable space in a smaller wet room.
  • Slower to heat the room compared to underfloor heating.
  • Costs range from £150 to £400 for a basic radiator, with installation costs around £200 to £300.

2. Underfloor Heating

  • Pros:
  • Saves space, as it is hidden under the floor.
  • Provides even, comfortable heat across the entire room.
  • Ideal for wet rooms due to its ability to dry out the floor after showers.
  • Cons:
  • More expensive to install.
  • Requires a sub-floor, which may add extra costs.
  • Costs: Underfloor heating can range from £300 to £500, with installation costs usually added on top.

Tips for Locating and Hiring Skilled Wet Room Installation Experts in Your Area

When hiring professionals to install your wet room, it’s important to ensure that the company or individual has the necessary experience and qualifications to handle such a specialised project. Here are some tips for finding and hiring skilled wet room installation experts:

Look for Specialised Wet Room Installers

  • Wet room installation requires specific skills, so it’s best to hire a contractor who has direct experience in installing wet rooms. Look for tradespeople who specialise in this type of work, such as plumbers, tilers, or bathroom designers with experience in wet room installations.

Check Reviews and References

  • Online reviews and testimonials from previous customers can give you insight into the quality of work provided. Consider checking platforms such as Trustpilot, Google Reviews, or Rated People to read customer feedback.

Verify Insurance and Qualifications

  • Ensure the installer has the appropriate qualifications (such as NVQ Level 2 or Level 3 in plumbing or tiling) and public liability insurance. This ensures that they are professional and covered in case of any accidents or damage during the installation.

Get Multiple Quotes

  • Don’t settle for the first quote you receive. It’s advisable to get at least three different quotes to compare pricing and the scope of work involved. This can help you find a fair price and understand what’s included in the quote.

Ask About Warranty and Aftercare

  • Reliable installers will offer a warranty for their work, typically ranging from one to five years. Be sure to ask about what is covered and if there are any aftercare services available.

FAQ's

How long does it take to install a wet room?

  • Typically, a wet room installation can take between 4 and 7 days, depending on the room size, the type of wet room being installed, and the complexity of the plumbing and tiling.

Can I install a wet room myself?

  • While it’s technically possible to install a wet room yourself, it's generally not recommended due to the specialised skills required. Waterproofing, drainage, and tiling all require a professional to avoid long-term problems such as leaks or poor drainage.

What’s the best type of flooring for a wet room?

  • For the best performance and longevity, ceramic or porcelain tiles are ideal for wet room flooring. They are slip-resistant, waterproof, and easy to clean. Other options include vinyl and stone, though they may require additional maintenance.

What are the most common problems with wet rooms?

  • Poor drainage: If the gradient of the floor isn't correctly sloped, water can pool.
  • Water leaks: A poorly sealed wet room can result in water escaping into surrounding areas.
  • Damaged waterproofing: It’s essential to ensure that all walls and floors are properly waterproofed to avoid damage.

A wet room is an investment that can modernise your home, improve accessibility, and potentially increase property value. Understanding the costs, labour requirements, and available options is key to ensuring a successful project. Whether you're aiming for a simple installation or a luxurious upgrade, a wet room can be tailored to suit your needs and budget.

Before you begin, it’s important to research skilled professionals and plan your budget accordingly. With the right planning, your wet room will not only enhance the functionality of your bathroom but also provide a stylish and practical space for years to come.
