Shower room under the stairs

[Eaglebird]

Has anyone fitted a shower room under their stairs, involving a Saniflo macerator?
We've had an offer accepted on a house, and are hoping to install a downstairs shower room under the stairs (there is enough room).
The kitchen will be in the room next door, so no probs getting a water supply in there, but we'd have to run the soil/waste pipe under the hall & dining room floor to reach the external soil pipe - so we'll possibly need a macerator/pump.
Just wondering if anyone's done this, and has any dos / don'ts or any tips to pass on.
Thanks.

havent done this but dont see why you would need a macerator unless its for cost reasons?

You need to have a drop in level of (i think)about 18mm per 1 metre of soil pipe, otherwise the flushed waste won't drain by gravity into the drain.
We might not be able to achieve this due to the shower room being under the stairs, and the main drain being several metres away. So we might have to fit a macerator/pump to pump the waste to the soil stack.

It would be a lot cheaper if we can get away with not fitting a macerator/pump, but it depends on how long the pipe run is from under the stairs to the foul water drain outside.

Was just curious to see if anyone had fitted a shower room / cloakroom under the stairs - or any other area which has no window, and no direct access to a soil stack.

Hi Eaglebird
we haven't got one ourselves but we have friends who have, I'll ask and see if I can find out.

I did this but not a macerator.The toilet was raised to get a fall and we ran a new soil pipe under the floor.Messier initially but macerators just not the same

We recently turned our upstairs en suite into a wet room and we had to use pumped drainage because there was no way to get a drain pipe out through the joists. We used one of these and it's been great. Not cheap though.

There are other models as well if you need it to pump higher.

We installed a new bathroom 2 years ago. Normal drainage would have meant
raising the entire floor in one bedroom and digging new drains on the outside, so we had a Saniflo Saniplus macerator fitted instead. It's been absolutely fine. We built it in fitted bathroom furniture as macerators are not attractive.

Thanks for your replies ladies.
We haven't exchanged contracts on the house yet, but are planning ahead.
We're hoping it'll be feasible to run the waste pipe under the floor and connect it to the external soil pipe / foul water drain; but if not, it'll mean a macerator/pump.
Victory, yes they are ugly so we we're considering a wall-hung toilet, and concealing the pump in a fitted cupboard.

How noisy are Saniflo macerators?
As noisy as an extractor fan? Hairdryer? Hoover? Aeroplane taking off LOL??
