Bathroom renovation
A complete bathroom needs several specialists. That is why one settled team of tradespeople works on your bathroom at Wrenfield, so the pipework, electrics, waterproofing, tiling and fitting all line up with each other.
Before and after.


Taken over after the work had stalled.
What we found
- Left half stripped, substrate exposed
- No record of what had already been done
What we did
- Mapped the existing situation, repaired the substrate
- Pipework and wiring pressure tested before anything closed up
- Falls measured, not guessed
- Waterproof layer with sealing tape in every corner
What we do.
- Strip-out and removal
- Everything out, back to bare substrate. Not half of it, because you cannot build on something when you do not know whether it is sound.
- Assessing and repairing the substrate
- Flat, dry and strong enough. If it is not, we put that right before anything else happens.
- Pipework and electrics
- Run new and pressure tested before anything covers it. After this stage you cannot reach any of it again without breaking something.
- Falls and waterproofing
- The falls measured rather than estimated, and a waterproof layer with sealing tape in every corner and at every junction.
- Tiling
- Full adhesive coverage under every tile, external corners mitred rather than hidden behind a trim.
- Grouting, fitting and sealing
- In the colour you choose, not whichever one happens to be in stock. Everything connected and tested before we leave.

- dark tiles
- round mirror
- freestanding bath

- black framed glass screen
- brass tap
- natural stone

- oval mirror
- green herringbone tiles
Why it works this way.
Every specialist under one roof
Plumbing, electrics, waterproofing and tiling are four trades. At Wrenfield those tradespeople work together as one settled team, and that is exactly why the work lines up: every trade builds on work by someone they know.
One project lead who checks every stage
Before the next stage starts, somebody checks the last one is right. That is exactly where a set of separate subcontractors falls down: everyone does their part and nobody looks at the whole.
You sign it off, and only then pay the balance
At the end you walk your own bathroom from one end to the other. Anything not right gets put right before the final payment. A firm that wants it all up front has no reason left to come back.
Questions everyone asks.
What does a bathroom cost?
It depends on what is behind your walls, which is the honest answer and the reason we look before quoting. The costs page shows how to build the figure up yourself so you can price any quote you are holding.
Where do I wash while the bathroom is out?
Most people use a cloakroom or a neighbour for the two to three weeks. We tell you at the survey exactly which days the water is off rather than leaving you to find out.
How do I know my bathroom was waterproofed properly?
You cannot see it once it is tiled, which is the problem. The self-checks on this page are the closest you get without opening anything up.
How long does a bathroom renovation take?
Two to three weeks. That is drying time, not slowness. Anyone promising it inside a week is compressing stage eight.
What guarantee do I get?
Five years on installation and fitting, one year on grouting and sealant, in writing. The market gives one to three years and sometimes nothing at all.
Is it better at my house or online?
At your house, every time. The whole value of the survey is somebody looking at the thing, and nobody can assess a substrate through a phone screen.
Am I committed to anything?
No. You get the report either way and you can take it to anyone. That is the point of it.
What if there is nothing wrong?
Then that is what the report says, and you have a written record that your room is sound. That is a perfectly good outcome.
Is your question not here? Ask it here and you will have an answer within 24 hours.
We come and look before a single tile comes off.
At your house or online, your choice. We go through all of it: the floor, the grout, the sealant, the falls, the waste. After that you know exactly what is going on and what will work in your room.
