Where’s the job?

Scope of Works

• survey existing drainage, joists and floor build-up to confirm feasibility of a level-access wet room

• strip out existing bath/tiles and prepare subfloor including any repairs to joists or timber

• reroute and install new waste and trap for linear or point drain, connect to existing soil stack or waste outlet and test for leaks

Typical Cost

Time on Site

Typical wet room installation takes 2–5 days on site for a standard bathroom conversion; allow up to 1–2 weeks where joists require strengthening, screed drying times are needed or additional trades (electrician, structural) are involved

Questions to Ask Your Tradie

• have you fitted wet rooms like this before and can you provide photos or references

• which tanking or waterproofing system will you use and what warranty does it carry

• how will you form the falls and what type of drain/waste trap will be fitted

• do you carry public liability insurance and will you provide a written estimate with a clear scope and timescale

• will any electrical work be required and are the electricians NICEIC or Part P registered where necessary

• what aftercare do you provide for leaks or defects and is there a workmanship guarantee

How to Avoid Surprises

• ensure easy access to the bathroom and reserve parking or drop-off space for materials

• expose the stopcock location and confirm water isolation before work starts

• clear fragile items and provide an area for storing tiles and materials inside the property

• check for any building regulation requirements or party wall notices that could delay work

• discuss ventilation and extractor provision up front to avoid condensation and mould issues

• make the tradie aware of pets and secure them during noisy or dusty work
