Shower drain under solid wetroom floor

Annie1960

My wetroom is now built and fittings will be installed soon.

I was thinking of getting vinyl which will also cover the shower area (no tray).

Is this a good idea, as what will happen if the shower drain needs to be maintained? How likely is this to leak?

Or should I get a shower tray which will allow access underneath if necessary?

I would prefer the look of vinyl only, but also want to take practicalities into account.

Sis had a wet room installed a couple of years back - Vinyl flooring wall to wall. Just make sure it is well sealed and curves up the wall all the way round.

Vinyl flooring for wet rooms is pretty common, especially in more commercial environments.

A good quality shower gully in the floor will have a removable grill on the top to allow access to clean it out, i would make sure however that the pipe from it is 2" and it runs directly outside on it's own with no bends or tee's added.

Where it comes thru the wall outside to tun towards a drain or soil stack i would get a tee with a rodding eye installed with the eye put into the tee piece so that allows you to look directly up the pipe towards the shower gully. In the event of a blockage or slow drainage this will allow you to clean back up the pipe from outside with relative ease

This will not be possible. Drains have already been installed and inspected by building control, and are underneath the floor.

All waste pipes should be installed in a way rodding access is given

There are various pre formed trays and gulleys on the market that allow for this.

The drawings for my new SVP at the side of the house mentioned rodding points, and I can see these in the new one.

However, the wetroom is at the front of the house and has 3 separate drain pipes installed in the floor. Building Control has confirmed to me that these are OK. I can't see any rodding points, but the floor is not finished yet.

Where should the rodding points be?

The rodding points are usually outside and can be on a sewer run or a waste pipe run, the three pipes that the builder has installed inside are probably 4" sewer, one for WC, one for WHB and the third for the shower drain.

You will want the wade (shower gully) gully installed beside this third sewer pipe as close as is possible (will depend on how close it has been put to where the shower is going to allow for a fall incorporated into the floor) to limit the length of the pipe run, all good shower gullies will have a removable grill on them to allow for cleaning and possibly some small amount of rodding with wire which is why you want as small a pipe run inside as possible with that setup.

Pipe run will be about 1.5 metres.

That's news to me - ie about bathroom drains being inspected by building control.

Does anyone have a link to any info. on that?

Having had my bathroom ripped out and re-fitted in this house recently and a rather different drainage set-up and there definitely was no inspection going on. Is that something that's only applicable to alterations to outside drains?

(It wouldnt surprise me - as the firm turned out to be a bad one....:cool:).

Drains are only inspected if a new connection is made into the sewer. If your just shuffling around the same connection then you can do as you please

Mine were part of an extension that went through planning and building control. However, I understand the connections inside may not need to, but the drawing did say the layout should be to the satisfaction of the customer and LA.
