WC into understairs pantry - nightmare

[Hugh Jaleak]

Use this https://mcalpineplumbing.com/plastic-chrome-fittings/drain-connectors/drain-connector-with-boss/ gets you as low as possible for the waste connection, and provides more flexibility with the shower waste options. You can soon drop down, you cannot come up.

Shower waste, look at a trap with a removeable insert, which will allow cleaning from above. Do waste runs in solvent weld pipework, and use swept bends rather than knuckle elbows, to aid flow and make future cleaning easier. Appropriate Traps on basin and shower (sinks are found in kitchens etc), and properly run pipework, keep it as short and straight as you can, and you should have no issues with odour.

Thanks. Make sense.

Did have a query about the Pantry floor. I was told it was quarry tiled floor and should not put plywood on top for lino as it would sweat. It does seem a bit damp as possibility there is no ventilation in the pantry currently.

Is it desirable to expose this traditional tiled floor? Can it be improved somehow, polished or cleaned easily?

Or if the floor is not that level, is it better to put some self level compound on it and finish it off with some flooring?
