converted bathroom into a wetroom

I converted my bathroom into a wetroom

Obligatory "after" shot. Converted my traditional bathroom into a 'wetroom' with underfloor heating, wall mounted vanity and LED mirror with demister. Apologies for the 'potato' quality on some of these pictures. They were all taken with an iPhone and a wobbly hand.
I don't have a decent "before" shot. I got carried away with ripping up the floor before I remembered to snap some pictures. Originally the house had a separate bathroom and toilet. When I first moved in I converted the bathroom, toilet room and part of a hallway into one larger bathroom, hence the weird orientation of the toilet.
Ripping tiles off. The old soil stack can be seen in the middle of the picture. This has always been a problem because it juts out into the room and was boxed in. Originally I never replaced it because I thought it was going to be a huge job.
Carnage. All of the interior walls on the upstairs floor of my house were built of brick, or to be more accurate, a 2" cinder block. I wanted to end up with a rectangular wetroom, so the original wall up to the original door frame had to go. This meant losing about 6" of bathroom space on one half of its width but it makes sense.
Removing tiles.
Removing plaster. The plaster was so old that it was practically falling off the wall and I needed a good sturdy substrate to work from.
I'm going to need to clean the bath…
In my previous bathroom refurb I'd hidden the pipes for the shower within channels cut into the wall. These had to go.
During the first refurb and because essentially three rooms we made into one, the ceiling was over-boarded with new plasterboard. This had to come down.
I hated that sink.
Getting there. Needed to take the room back to a bare shell.
Yuk. Years of poop have gone down this pipe. It didn't smell too good.
The asbestos cement portion of the soil pipe which exited through the roof was successfully removed with some help from my Dad.
Time to cut off the old cast iron soil pipe section so it will finish below the floor and can be capped off. Had some help from my Dad with this part too… we took it in shifts on the angle grinder. We had to use a 4" grinder because access was so tight.
The plumbing was time consuming. All of the cold and hot feeds into and out of the combi boiler ran through the bathroom. Much re-routing was required.
Back to a bare shell.
There was a lot of plumbing work to do. I had to re-route pipes for not only the shower, sink and toilet, but also the boiler and the towel rail.
Something for the next renovator to find 🙂
More plumbing complexity. Opted for end-feed fittings as they are cheap and never leak if done right. Push-fit fittings are handy, but expensive and bulky.
Sealing up the remnants of the old soil pipe as only the upstairs section needed to be removed using a section of polythene sheeting and expanding builders foam. Removing the bottom section would have involved smashing my kitchen to pieces which wasn't really something I wanted to do.
Because of the routing of the original soil pipe, there was some weirdness with the joists. It would have meant having a fairly large unsupported section of floor which obviously is not ideal. A new section of joist was installed using chemical fixings, joist hangers and some hefty thread and bolts.
In old, ex-council houses there is no such things as a straight line. Everything slopes. The original bathroom floor sloped towards the door. After removing the floorboards I cut and fixed shims to the tops of the joists to level out the floor and provide a very subtle slope towards where the wet room drain.
Testing placement of the wetroom tray former.
Building a support deck for the wetroom tray former using WBP plywood. Insulating the floor cavity at this end of the room as it is above an alleyway that allows access from the front of the house to the back yard. The alleyway is pretty much open to the elements hence the insulation.
Starting to lay the new floorboards.
Safety first. This is more for future owners of this home than me.
New subfloor laid. All boards were fixed with specialist flooring screws and all joints on the tongue and groove glued with water/acid/salt resistant, expanding glue.
Floor treated with Thompsons Water Seal. If this floor is ever exposed to moisture, something has gone seriously wrong, so this was probably overkill. All pipe runs marked on floor boards.
Wetroom deck fitted and floorboards over-boarded with WBP ply to stop bounce and deflection in the floor.
Impey Wetroom tray former fitted with adjustable outlet.
New ceiling plasterboard fitted and LED downlights. New door frame in foreground.
Battens fixed to the party wall (my neighbour's house is the other side of those bricks).
Vapour barrier installed prior to fixing AquaPanel cement boards. Don't want any kind of damp getting through to the party wall.
AquaPanel fitted to party wall. Joints sealed with silicone.
Dry-walling ceiling. Joints taped and filled.
Building a false wall behind which all of the pipes will be hidden. Also to allow room for the shower, half of the far window will be boxed in.
Building another false wall for the opposite side of the shower. This will allow a recess where shampoo/shower gel etc can be placed.
AquaPanel installed around shower enclosure. Shower controls installed on the left.
Flexible outlets for shower head connectors installed. The blue stuff on the AquaPanel is BAL waterproof PVA which is required as a primer before installing the tanking.
In the areas of the room which will not be exposed directly to water jets moisture resistant plasterboard was used (which is why this is green/blue not grey).
Galvanised steel channel to protect wiring for underfloor heating and the heated/illuminated mirror. These will be behind tiles anyway.
More dry-walling using moisture resistant plasterboard.
AquaPanel jointing tape. Unlike the usual paper stuff this is resistant to water, chemicals, salt and nuclear winter.
Big hole for the extractor fan. Required to remove steam and moisture from the room as well as the smell of my turds.
More boarding completed and extractor fan wired in to the lighting so it comes on when the lights are switched on.
Installing the tanking kit jointing tape. This is what makes the wetroom waterproof.
Impey self-adhesive tanking kit fully installed and joints sealed.
Electric underfloor heating mat installed. Gap left for toilet (bottom left).
Thin layer of self-leveling compound added to floor to both protect the underfloor heating mat and to provide a smooth flat surface onto which the tiles can be laid.
Floor tiles laid. Went for a concrete effect, porcelain, non-slip floor tile.
Feature wall tiled with standard ceramic tiles.
Feature wall tiled with standard ceramic tiles.
Starting to tile the rest of the walls with large format porcelain tiles. A feature mosaic band runs around the middle of the room which is the same colour as the rest of the tiles.
Tiling almost done.
Recess for shower goodies.
Toilet and vanity unit fitted.
All done. Needs a thorough clean though and the towel rail is yet to be fitted..
New external, modern, PVC soil stack. The top vent part is too high and need to be shortened, but at least I can have a shower now 🙂
I also stuck googly eyes onto my shop vacuum.
