I have been involved with waterproofing products for wet rooms for more than 15 years. During this time I've received several phone calls and e-mails from folks that have wanted a wet room but have been told by their builder / pal / dog sitter's neighbour! "You cannot have a wet room on a second story". I would like to point out, when and for all, that yes, you can produce a wet room around the very first floor, second floor or any other floor. You can also produce a wet room on a wooden floor in addition to on concrete floors. Yes it may be done, no it isn't difficult and no you will not get leaks (providing the work is carried
In looking at the benefits and drawbacks of this issue, it's intriguing to consider the main differences among a traditional shower area and a wet room.
Having a standard shower area the shower tray itself is waterproof, but the rest of the room is usually not waterproofed at all. Any water that by-passes the confines in the tray has no way of getting into the waste method and can as an alternative leak
by means of in to the floorspace, rotting timbers or leaking into rooms under. When the shower is first installed you would hope that the installation will be watertight, however over the years silicone sealant becomes hard and significantly less flexible, grout among tiles can crack and "water resistant" tile adhesive can break down. Several, a lot of people more than the years have had difficulties with leaking showers, and normally by the time the problem is found a whole lot of water harm has already occurred.
We are able to contrast the above using a properly installed wet room. Firstly the trapped waste outlet is installed at floor level. The floor is sloped down slightly (slope to falls) to make a gradient towards the waste. As water naturally desires to run downwards we are able to realize that providing it really is contained, the water will run towards the lowest point inside the room, where it'll enter the shower outlet as well as the waste water method. There's no way for water to bypass the waste outlet. The important towards the good results of this arrangement is waterproofing (also referred to as tanking). All wet rooms should be tanked, this must extend towards the entire floor location, with a turn up of at the very least 100mm on to the walls. All walls inside the immediate shower area ought to be tanked floor to ceiling. In this way any water that seeps by means of the tiling will likely be contained by the waterproofing. It's going to run downwards and will harmlessly enter the drainage system. We are able to as a result deduce that a wet room is a very safe proposition in comparison to traditional shower installations.
In terms of the ease of making a wet room, essentially the most difficult point in people's minds seems to become producing the "slope to falls". This could be quite demanding if undertaking all the joinery from scratch, nevertheless the smart way of reaching the needed "falls" is by utilizing a Shower Tray Former. A shower Tray Former (also referred to as a "hidden shower tray") is a pre-manufactured tray with the gradient currently constructed in. They are usually flat on the back and fit directly over the floor joists, using a sloped front surface. The ones I am familiar with are made from environmentally friendly Birch Ply and are rebated able to install the included wet room waste outlet. When the tray is installed it's then waterproofed in addition to the rest from the floor, and will be tiled over, giving a continuity of style across the entire floor. All you are going to see of the former within the finished floor will likely be the grating, everything else is hidden.
When tiling over a wooden floor it's very important that the floor is rigid. If there's any "bounce" in the floor, then this can have to be eliminated by utilizing additional "noggins"(additional joist installed in between the current joists, at a 90 degree angle). The flooring construct up also needs to be really thick, I would recommend a minimum floor board specification of 20mm WBP Plywood, but 24mm is even much better!
The waterproofing system used must be of a type specifically developed for wet room designs
rooms. Normally they consist of a liquid rubber paste with extra re-enforcing tapes, sleeves and cloaks for wall to floor junctions, pipe penetrations and corners. The waterproofing needs to be flexible, very temperature steady and breathable, inside the European Union such waterproofing systems should conform to ETAG 22 and carry the CE markings.
