If renovating your bathroom is your next home improvement project, you’ve a great opportunity to strip it out and start from scratch.

But, make sure you plan, design and price it up correctly to avoid costly mistakes.

Designing a New Bathroom Layout

Firstly, draw up a plan of your current bathroom to scale on graph paper. Mark down plumbing, windows, doors and the sanitaryware.

You’ll see snaggy spots that don’t work that you can lose and the bits that you want or have to keep.

Once you’ve got your existing bathroom design plotted out you can start to play around with the layout.

At this stage, think about who uses the space as this will give you a focus. Is it a family space? A guest bathroom? Or an en suite?

A space fit for the whole family

If you want to renovate to create a better functioning family space then adding a bigger bath or more storage could be a practical move.

Similarly, ask yourself if you can move sanitaryware around to create a better layout that works for all the family.

If space is tight and your bathroom is small think about introducing wall hung basins and units. They open up the floorspace creating the illusion that the room is bigger than it is.

An en suite

If you’re designing a luxurious en suite include statement pieces like a raindrop shower head or a roll top free standing bath. Or go all-out and design a wet room.

But there’ll be work involved to make the wet room installation watertight. You’ll want to avoid any nasty leaks ruining rooms adjacent or below.

Twin Shower Panels

Create the ultimate in luxury with twin showers, like this stunning example featuring twin shower panels from Merlyn Showering. Prices start from £354 per panel.

Are You Remodelling or Updating Your Bathroom?


Remodelling a bathroom often means you’re thinking about moving things around or creating a bigger space. For example, bringing together a separate WC and bathroom. Remodelling also means more work. Plumbing will need to move to accommodate the new layout so think about what impact this will have on the design and your budget.

Your layout plan will come in handy here. You can discuss the relocation of plumbing/pipework at the design stage with your plumber and builder.

Updating the space

If you’re happy with the current configuration or you want to keep costs down by keeping plumbing in place, then the design is a lot more straightforward. You’ll already have your layout partly done.

So, think about how you can create a more functional bathroom with the configuration you have: space for a shower cubicle if you haven’t already got one, built-in storage shelves, a heated towel rail or underfloor heating (UFH).

Bathroom Renovation Checklist

It’s easy to get caught up in the design and forget about the function, so use this simple checklist to cover all areas of your bathroom renovation design and budget:

  • The plumbing & soil stack: Is it moving or staying put?
  • Heating: Think about UFH and heated towel rails
  • Flooring: Pick a style that’s non-slip, easy to clean and suitable for wet areas
  • Lighting: A bathroom is zoned so make sure any lighting conforms to regulations
  • Wall covering: If budget is tight, tile just around the shower/bath and basin and paint the rest of the wall.
  • Storage: Do you need more? Where can it go? Can it be built-in?
  • Sanitaryware: Shop around and do your research, it pays to be a savvy shopper.

How Much Will a Bathroom Renovation Cost?

The average cost of a new bathroom is from around £3,000+, but this will vary depending on the size of your renovation project and the level of luxury you’re going for. Likewise, if you’re doing a lot of the work yourself, on a DIY basis, then this will bring your costs down.

A plumber should take two to three days to remove your old bathroom and retrofit your new one, which will cost around £1,000.

If you’re factoring in a tiler, a small bathroom would take one to three days and cost between £350 and £800.

Prices are dependant on the tiles and sanitaryware you specify.
