The most common plumbing project people take on is not a bathroom refit or a new boiler. It is squeezing a toilet in downstairs, usually under the stairs, in a corner of a utility room, or in the space by the back door.

It is also the project most often planned in the wrong order, because people decide where they want it and then find out whether it can go there.

Start with the waste, not the space

A toilet needs a route to the soil stack, and that route needs a fall along its length. That single requirement decides more about a downstairs cloakroom than the room size does.

  • Close to the existing stack. Straightforward. A short waste run at the right gradient, boxed in, done.
  • Further away, on a suspended timber floor. Usually possible, since the waste can run between joists, though the direction the joists run may not be the direction you need.
  • Further away, on a solid concrete floor. This is where it gets expensive, because achieving a fall means either breaking out the floor or building a raised plinth for the toilet to sit on, which is not always acceptable to live with.
  • Nowhere sensible to run at all. A macerator becomes the option, pumping waste through small bore pipe that can run uphill. Genuinely useful, and worth understanding the trade-offs first: it needs power, it does not work in a power cut, nothing but toilet paper can go into it, and it should not be the only toilet in the house. See macerators and Saniflo.

The other three questions

Ventilation. A room with no openable window needs mechanical extraction, and it needs to terminate outside rather than into a loft void.

Water supply. Straightforward for a basin and toilet, but worth checking whether adding a shower would leave enough flow for the rest of the house. On a combi the incoming mains is shared between outlets.

Under the stairs specifically. Headroom is the constraint people forget. You need usable height in front of the toilet as well as above it, and the space narrows exactly where you need it.

The order that works

  1. 1

    Confirm where the waste can physically go, before anything else

  2. 2

    Decide gravity or macerator based on that answer, not on preference

  3. 3

    Then design the room around it

  4. 4

    Then buy the fittings

Doing it the other way round is how people end up with a suite in a garage and a layout that will not work. See bathroom plumbing and toilet installation.

The housing in Willen Park

1980s estate housing on the eastern side of the city, next to the older hamlet at Willen. Second and third generation boilers now, gravity hot water in many properties where converting to an unvented cylinder is the biggest single improvement available, and enough space in most of the layouts that a downstairs cloakroom is a realistic addition.

Hard water

Same Anglian Water supply as the rest of Milton Keynes, around 300 mg/l of calcium carbonate against a UK average of 207. See our hard water guide.

Questions

Frequently asked questions

Can I put a toilet under the stairs?

Often, and the waste route decides it rather than the space. Headroom in front of the toilet is the other constraint people forget.

What if the waste cannot run there?

A macerator is the alternative. Useful, and worth knowing it needs power, will not work in a power cut, and takes nothing but toilet paper.

Do I need a window?

No, but you do need mechanical extraction terminating outside rather than into a loft.

Can I add a shower downstairs too?

Usually, though on a combi it is worth checking the incoming mains flow can support another outlet without weakening the others.

Do you cover Willen and Downhead Park?

Yes, along with Pennyland, Great Linford, Tongwell and Blakelands.
