OK here is the plan - any comments or suggestions appriciated.
Replacing En-suite bathroom. This so far has entailed ripping out the old
bathroom, lifting the chipboard flooring, and replacing with new chipboard.
Some boarding around the edge of the room has had to be left, in place,
since it comes from the other side of a stud partition wall. This (and the
new boards) will be varnished with two coats of polyurethane varnish. In
addition, I will be fitteing an "aqualoc" laminate floor (supposedly
suitable for bathrooms), with a water proof membrane underneath. The
membrane will be run up the wall behind the skirting to minimise the risk of
water getting to the chipboard.
Shower tray will be resin cast, on a platform constructed from 2x4 timber
and 18mm ply. It will be bedded on cement. Gap between wall and tray will be
filled/sealed with expanding foam filler.
I'm going to use "aqua panels" behind the shower - I'm not interested in
trying to ensure all the grouting is water proof. These will be fitted to
battons on the wall, which will allow the shower water supply to go behind
the aqua panels. This has the added advantage that the panels will be
further away from the edge of the tray, minimising the possibility of leaks.
The panels will be glued in place, excpet for two (mirror) screws at the top
to hold in place while the glue dries. There will be a 5mm gap between the
bottom of the panel and the shower tray, to fill with silicone sealant.
Shower will be a power shower with built in pump. I will need to run a new
gravity fed cold feed for this, but will T-off the existing basin hot water
supply, since this will not be used at the same time as the shower. Power
for the pump will come from the old (removed) electric shower circuit (Fused
pullcord), which will also be used to provide one additional socket on the
landing (is there anything in the regs which should stop me doing this -
circuit is 32A fused)
Shower will be fitted first, then walls tiled, and floor fitted. (Intention
is to get shower base on the most solid floor possible (ie not on top of the
laminate) Finally Basin unit and Toilet will be fitted on top of the
flooring. All plumbing to have individual isolating ball valves.
Thats about it. Anything I've missed? Am I doing things in the wrong order?
Any other suggestions?
