Frequently Asked Questions
How long does a full bathroom installation usually take?
Timescales depend on scope: a simple replacement with like-for-like sanitaryware can be a few days, while a full strip-out with new pipework, tiling and waterproofing will take longer. We provide a realistic programme after the survey and aim to minimise time on site.
Do you handle the waterproofing and tiling as well as the plumbing?
Yes. Our teams install waterproof membranes, tile substrates and finish with tiling that meets industry guidance. Waterproofing is treated as a priority around wet zones and is included in our standard install specification.
Can you install underfloor heating under new bathroom tiles?
We can supply and install electric or wet underfloor heating systems and integrate them with the existing heating controls. Underfloor heating is planned during the design stage so screed, insulation and tile choices are all correct for efficient performance.
Will you remove my old bathroom and dispose of waste?
Yes, we include removal of existing sanitaryware and responsible disposal of waste as part of the installation. We leave the house tidy at handover and inspect all finishes with you before signing off the job.
Do bathroom installations need Gas Safe or OFTEC work?
Any work affecting gas appliances, boilers or fuel-burning hot water cylinders requires Gas Safe or OFTEC qualified engineers. TJ&H is accredited for both, so we carry out required connections and safety checks and provide the necessary certification.
