Nasty Niff..

[ferlew]

Fortunate enough to have had a wet room installed instead of the en suite -
unfortunately the bathroom has a nasty odour from the bath and basin no longer being used .....what can I put in regularly to stop the stink?

have you got a dead something under the bath....?

It'll help if, on a regular basis… say once a week, you'll run water into the bath and basin for a minute or so.

What happens is the water held in the "gooseneck" trap under the bath and basins are designed to keep sewer gas and associated smells from coming up into the room evaporates if not used fairly often… replacing the water lost to the evaporation should help...

is the bath and basin still in the en suite/wetroom - could be trapped water similar to what clanad says and you may need to open the grid/grille on wetroom floor and remove any hair and stuff clogging it - I've a wetroom and have to do this regularly (a job I hate)

no wonder you had peumonia, ducksie.....all that 'hair' and the rest, luvverly.

Thanks DTC :) I've been doing it years - give me an oven to clean anyday :)

I pop a little Jeyes Fluid down the plughole every couple of weeks or so.

No problems in the new wet room, (ensuite).
I think the problem is because we no longer use the bath in the main bathroom, just the basin for hand washing after loo use.
I'll have a go with Clanads idea for the next week or two, thanks you.

Evaporation in the traps, ferlew....... described perfectly by Clanad.

Other than evaporation, a common cause is syphonage. Often happens when waste pipe runs are altered to accommodate new basins, showers etc.

If the waste pipework is simply added to rather than run separately, then one trap (U-bend), as it empties, can cause water to syphon from other one on the system. Listen out for gurgling in the old traps when the new basin or shower are emptied.

See how it goes. If you suspect syphoning, then it's easy to rectify by swapping the old basin and bath traps for anti-syphonage ones.

The Builder...in view of the fact this place was built in 2002, do you think that may be the case ?
As far as I can make out... the pipework was re-used rather than diverted or added to.
Old en suite was loo, basin, electric shower cubicle.
New wet room is loo basin shower run off the mains and the usual wet room flooring and wall treatment.

It will depend on where the wastes drain (position of soil stack - usually a big, boxed in pipe in the corner.) Also, is the wetroom right next to the old bathroom?

If the two rooms are some distance apart, and do not share a soil pipe, then it would probably not be syphonage but simple evaporation.
