Service Overview

Bathroom Renovations —
The Brief, In Plain English.

What It Is

A bathroom renovation strips a tired or failing bathroom back to brick or stud and rebuilds it as a properly waterproofed, properly serviced wet room or family bathroom. Strip-out, replumb to current regs, tanking, screed, underfloor heating where wanted, tile, grout, silicone and fit-out.

Who It's For

Homeowners replacing a tired bathroom; landlords turning round rental bathrooms between tenancies; renovators rolling a bathroom into a wider scheme; anyone who's been quoted by a bathroom showroom that supplies but doesn't fit, or a fitter who doesn't tank.

When You Need It

Once you've settled on the layout and the suite, and the rest of the house programme allows for 7–14 days without a working bathroom — or with the right family logistics, longer.

Why It Matters

Bathrooms fail at the tanking step. A bathroom fitted by a kitchen fitter, plumber or general handyman skipping the tanking system will leak into the ceiling below inside 12–24 months — and the damage is structural, not cosmetic. The unglamorous bits decide the lifespan.

What Happens If You Wait

The Cost Of
Doing Nothing.

A leaking bathroom is the most expensive failure in domestic construction. Joists rot, ceilings come down, insurance gets argued.

Risks Of Ignoring It

  • Wet rooms tiled before tanking — water in the joists, ceiling down below within 18 months.
  • Pipework run in floor voids without access — first leak means a floor up.
  • Tile grout failing because of substrate movement — water gets behind the tiles.
  • Silicone bead applied over dirty surfaces — peels off, water tracks behind.
  • Wrong board behind tiles — paper-faced plasterboard under a shower, not tile-backer.

Common Mistakes Customers Make

  • ×Buying the suite before measuring up properly.
  • ×Letting a kitchen fitter 'do the bathroom too'.
  • ×Skipping underfloor heating then regretting it forever.
  • ×Specifying glass-only screens where a half-height wall would work better.

01

Survey & Spec

02

Fixed Written Quote

Itemised written quote — strip-out, plumbing, tanking, tile spec, suite, second fix, decoration.

03

Strip & First Fix

Bathroom stripped to brick or stud, pipework reset to current regs, electrical first fix, tile-backer board where required.

04

Tank, Screed & Tile

Full tanking system to walls and floor in wet areas, screed to fall, underfloor heating laid, tile and grout to spec.

05

Fit & Sign-Off

Suite installed, silicone beaded properly, tested under pressure, snags fixed same day, paperwork handed over.

Why It's Worth It

What You
Actually Get.

Tanking Done Properly

Full liquid or membrane tanking system to walls and floor in any wet area — the bit that stops your ceiling coming down next year.

Water Where It Belongs

Falls cut into the screed, pipework pressure-tested, traps accessible, silicone beaded to clean surfaces. No surprises.

Tile-Ready Substrate

Tile-backer board behind tiled walls, not paper-faced plasterboard. The substrate decides whether the tiles still look right in five years.

Underfloor Heating Option

Wet or electric UFH laid under tile when specified — quiet, even warmth and no ugly radiator on the wall.

One Quote, One Team

Plumber, tiler, electrician and joiner all run on one programme by one accountable team. No three-trade booking dance.

Full Service Area Map

Family Bathrooms

Bath plus separate shower or shower-over-bath, vanity unit, WC and storage to a domestic spec built to last the next 10–15 years. Standard suite or your supplied kit.

Wet Rooms & Walk-In Showers

Fully tanked floor and walls, screed-to-fall, linear or point drainage, frameless glass screens, large-format tiles. The bit that fails most often when done by anyone but a properly trained fitter.

En-Suites & Cloakrooms

Compact layouts where every millimetre counts — pumped soil systems where gravity won't reach, slimline suites, sliding or pivot doors. Same tanking standard as a full bathroom.

Rental & Landlord Turnarounds

Hardwearing, easy-clean specs designed for tenant turnover — durable tile, simple silicone joints, accessible plumbing for the next leak fix. Fast programme between tenancies.

Period Property Sensitivity

Bathrooms inside Victorian or Edwardian terraces sometimes need solid-wall detailing — lime-friendly fixings, breathable build-ups where possible, and pipework routes that don't notch joists into oblivion.

Questions

Straight
Answers.

Cost, timeline, guarantees, lifespan, emergency availability — the questions everyone asks, answered before you call.

Ask Yours

How much does a new bathroom cost in South Wales?

+

Cost depends on suite spec, tile choice, layout changes and any structural work. We give itemised fixed written quotes after a site visit so you can see exactly what each element costs.

How long does a bathroom take to fit?

+

A straightforward replacement bathroom is typically 7–10 working days. A full strip, replumb, tank, tile and fit usually runs 10–14 working days. Wet rooms with screed-to-fall and underfloor heating add a few days.

Do you supply the bathroom suite or do I?

+

Either works. We can spec through trade suppliers we trust or fit suites you've bought yourself — just want to see the spec before pricing labour so we don't undersize a soil run.

Do you tank every bathroom?

+

We tank every wet area as standard — full tanking system to walls and floor inside shower enclosures and wet rooms. Family bathrooms with bath-only get the wet zones tanked.

Can you install underfloor heating?

+

Yes — wet or electric, laid under screed before tile. Specify at quote stage so we set the floor build-up correctly.

Will I be without a bathroom for the whole job?

+

Yes — once the strip starts the room is out of action until the end. For households without a second bathroom we'll talk through options before quoting.

Do you take a large deposit?

+

No. We work on stage payments against completed milestones, not large up-front deposits. You're paying for work done.

Do you handle electrical certificates for the bathroom?

+

Yes — Part P electrical work is signed off and certificated, bundled into the handover paperwork.
