How much does a new bathroom cost?

Bathroom costs vary because every room starts in a different condition. The suite you choose matters, but the preparation behind it often matters just as much.

What affects the price most

The biggest cost factors are the size of the room, how much tiling is needed, whether the layout is changing, the condition of the floor and walls, and the quality of the products being fitted.

A like-for-like swap is usually simpler than moving a toilet, creating a walk-in shower, changing electrics, replacing damaged flooring or fully tiling the room.

The costs people forget

Customers often think about the visible items first: bath, toilet, basin, shower, tiles and furniture. A good quote also needs to allow for removal, waste, pipework, waterproofing, plastering, electrics, ventilation, sealing and finishing.

Those hidden parts are not as exciting as choosing tiles, but they are what help the bathroom last.

How to control the budget

Keep the layout sensible where you can, choose products before work starts, and avoid changing your mind once plumbing and tiling are underway.

It is also worth keeping a small allowance for hidden problems, especially in older homes where floors, walls and pipework are not always obvious until the old bathroom is removed.

Budget checks

  • Ask what is included and what is not included in the quote.
  • Check whether waste removal, plastering, electrics and finishing are allowed for.
  • Choose tiles early so the labour and material quantities are clear.
  • Be careful with very cheap products in high-use bathrooms.
  • Keep a sensible contingency for hidden repairs.
