Hi everyone,
First a quick bit of background : I'm English, living in France, and renovating a 1960s house, which has pretty much needed to be stripped back to the studs, and started again. Full new electrical refit, plumbing refit, walls, ceilings &etc. It took about a year-and-a-half (as it's a DIY "project") to strip internally, and we're now rebuilding. Living in it as well, and we have sufficiently finished (haven't installed architrave for the doors / skirting boards for example) a Kitchen, Living Room, Dining Room, and 2 Bedrooms. Note the absence of "bathroom". We have a bit of a "Heath Robinson" set up for the toilet and bath, which works, but is far from ideal. Next room to tackle, though, will be the bathroom.
So - here's my question / request for help.
Our floors are all pretty solid concrete; sometime with breeze block equivalents, but they're basically 23cm or so thick. I want to install a shower tray in the bathroom, and all of the standard solutions for a trap have a horizontal exit with a 45o connector. This is ideal for houses with floor boards and beams - plenty of videos on SkillBuilder / Youtube / PlumberParts, but installing this in a solid concrete floor would be a nightmare, plus the risk of loss of structural integrity, I would imagine.
I've come across a few vertical traps, which look like they might be the solution (less drill out of the floor), like this one
www.victorianplumbing.co.uk
which would / should enable a single vertical drill hole though to the floor below, which I can then take through a false ceiling to the 100mm stack.
If you've ever used these, I'd appreciate your feedback on this as an idea ? Also, I would ideally want to have, in the ceiling below, a 90o bend to reduce the loss of the ceiling height (in the false wall), but is that just foolish ?, or should I go for a long sweep (or, realistically, 2 x 45o joints)
Thanks in advance for any suggestions / feedback &etc.
Cheers
Steve
