Downstairs WC

3DataModem

Hi,

Looking for some help.

Parents in law considering a downstairs WC. They have an under stairs space and a large garage both would have space.

The problem is there are no services to either spot, as far as I know.

Can someone give me an idea of the options for a simple toilet and sink? I've heard saniflow can work well? Do floors need to come up to put in services?

I know it depends on the house, but any pointers or tips or ideas of cost (and how long it takes) would help.

Cheers

It's a real how long is the string. Saniflow can be great but only as a last resort.
Photos the layout of the house if you can

Yep, Saniflo can do it but it's much better not to use one if you can avoid it.

To do it without a saniflo, you need to be able to run a 4" pipe, with a 'fall' to allow drainage by gravity, to the foul sewer, which is basically where the pipes from other toilets in the house flow out of the house and go into a manhole. Find the manhole, figure out if there is a route, and that will give you some idea of how complex it is. Even finding out where your manhole is will make things run a lot more professionally when you go to get quotes, etc. You also obviously need to run hot and cold supplies from the hot press or elsewhere, but this is only half-inch pipe and is much easier to run.

With small bathrooms like this, the expense and time is often in the finishing as much as the basic plumbing. It is hard for the tradesman/women because he/she is working in confined spaces. You will be (and should be really) demanding quite a high standard of finish.

We did this about 20 years ago. It all depends on layout – It was very handy for us. We have wooden floors with about a 2ft gap underneath, so a good fall. From under the stairs the sewer pipe ran under the kitchen and out the back wall, where it met the pipe coming down from the bathroom, which was over the kitchen. This was cut just above ground and a connector was fitted. The hot and cold for the wash basin came from the kitchen – all done under the floor. The waste connected into the sewer pipe close to the toilet. We have never had any problem since we did it. Instead of a window, we have an extractor fan that switches on with the light and continues to run for a few minutes after being turned off.
I know of others that went out through a side wall and ran a trench to the sewer.

You probably need to follow the part of the Building Regulations dealing with disabled toilets - Google that topic for details of layout/s. Do or get someone to do a basic sketch for you.
