How an en-suite renovation is done, step by step

1Protect, patch & clean
About half a day with a trade
- Clear the room and cover floors, stairs and doorways you walk through
- Fill holes and cracks; patch-plaster any big damage
- At the end: hoover, wipe down, remove protection
2Strip out & skip
About half a day with a trade
- Water off and pipes capped by a plumber before anything comes out
- Rip out old suite, tiles and flooring into the skip
- Check walls and floor for rot, damp or loose boards now, not later
3Bathroom suite & plumbing
About 6 days with a trade
- First fix: plumber runs new pipes and wastes
- Shower walls boarded with backer board and tanked
- Bath and shower tray in before tiling; toilet, basin and taps after
- Pipes boxed in, silicone done, everything tested for leaks
4Wall tiling
About 1.5 days with a trade
- Walls primed; shower area tanked
- Tiles set out from the centre so cuts are even
- Leave 24 hours, then grout and wipe off
- Silicone the corners and edges, not grout
5Paint walls, ceiling & woodwork
About half a day with a trade
- Fill, caulk gaps and sand
- Mist coat on new plaster, then ceiling first
- Two coats on walls
- Woodwork last, in satin
6New flooring
About half a day with a trade
- Ply overlay screwed down every 150mm so the floor can't flex
- Undercut door frames so the floor slides under
- Lay the LVT, staggering the joints
- Door bars to finish
7Finishing touches
About half a day with a trade
- Light fittings and new socket fronts on (power off at the fuse board)
- Blinds or curtain poles up
- Door stops on so handles don't hit the new paint

Easy to forget

Plan for no bathroom for 1–2 weeks. Is there another toilet?
Tank the shower area before tiling. Leaks here cause the most damage
An extractor fan is a must, or you'll get mould
Flooring goes down after painting, so it doesn't get splashed
Order everything at least a week before you start. Waiting on one part stops the whole job
Keep 10% spare. Old houses always hide something behind the walls

Questions people ask

How much does an en-suite renovation cost in Northern Ireland in 2026?

A mid-range en-suite renovation costs about £5,400 – £7,200 for a typical 2.2 × 1.6 m room with trades doing the work, including materials, labour and a 10% contingency. Budget finishes start lower and premium can cost a lot more; see the table above.

How long does an en-suite renovation take?

About 10 working days of trade time on site, plus around 1 days waiting for plaster, adhesive or deliveries. Allow roughly 3 weeks start to finish, longer if you do parts yourself.

How much can I save by doing some of it myself?

Doing the DIY-friendly work yourself (protect, patch & clean, strip out & skip, wall tiling, paint walls, ceiling & woodwork, new flooring, finishing touches) saves about £1,000 on a mid-range en-suite. Leave bathroom suite & plumbing to qualified trades.

Do I need building control approval?

Usually not for a like-for-like refit. You will normally need building control approval if you remove or alter walls, change drainage, make a new opening for a window or door, add a toilet or bathroom where there wasn't one, or install or replace a boiler. If in doubt, ask your council's building control team before you start.

Do I need to tank the shower area?

Yes. Tanking is a waterproof layer under the tiles in the shower area. Leaks from an untanked shower are the most common cause of expensive damage after a bathroom refit.

Does an electric shower need a new circuit?

Usually yes. An electric shower needs its own circuit from the fuse board with the right size cable, fitted and certified by a qualified electrician.

Are there grants for this?

Not usually for a straightforward en-suite refit. If you're adapting a home for someone with a disability, you may qualify for a Disabled Facilities Grant through the Northern Ireland Housing Executive, which starts with an occupational therapist assessment. Check nidirect for the current rules.

Is this a quote?

No. These are guide prices from RenoLab's pricing engine (price book v2026.10), built on Northern Ireland trade rates and current UK retail prices. Put in your own sizes for an itemised price, then get written quotes.
