Walk-in showers can feel out of place or in the way if they’re in the middle of the room since they’re so big. Putting the shower in the corner also makes it easier to contain splashes. Most contractors suggest about 6 feet of open space around the shower - anything closer will be in the splash zone. HGTV shows you how to upgrade a bathroom by installing a walk in shower. This easy step-by-step process. Wetroom and Walk-in Shower – How to Convert Any Room in Your Home into a Walkin Shower Room or Wet Room Building a wet room or walk in shower, turning a bathroom or toilet into a wet room and keeping a wet room waterproof. In this handy guide we run you through all you need to know in order to convert a room into a walk in shower room including how to correctly prepare the room, how to lay a walk in shower tray on both concrete and timber floors and then how to tank and tile your wet room so that it stays waterproof. ![]() Complete install of a modern wetroom Wet Rooms on the Ground Floor For years wetrooms and shower rooms were limited to ground floors and had to be sited on a concrete, or at least screeded, base. With new technologies, particularly around ways to manage the expansion and contraction of all materials used in modern house construction, it is possible to put a wetroom anywhere in the home, including the loft and providing the work is done properly it does not matter if it is a wooden floor in the room you wish to use. Preparation for Wet Rooms The first thing to understand about a conventional wet room is that it will only ever be as waterproof as the surface used to line it. This surface, be it porcelain tiles, ceramic tiles, tile backer boards, liquid rubber membranes or some other kind of latex or vinyl waterproof covering, will not remain waterproof if the surface it is stuck (or otherwise fixed) to is not completely sound. The first step therefore, when creating a wet room or shower room is to make sure that the floor is not loose in any way and the walls are a) not loose and prone to excessive movement and b) have not got a flaky surface. Surfaces must also be entirely free from dust, debris and grease. ![]() Different Ways to Construct a Wetroom Although all of the possible ways to complete your project we mention on this page are great ways of achieving your dream, they can all be very easily spoiled by lack of preparation. Tomtom updates 2018. As you will, or even see on the, when tiling a bathroom under normal situations, it is not necessary to tank the walls or provide any kind of tile backing board. The tiles themselves, if laid properly, will give you a waterproof surface. However; when constructing a wetroom the tiles (although they should still be laid properly) are more for form than function. There is simply too much water in a wet room to depend on the tile grout proving a completely waterproof area for very long. To construct a great wet room or shower room the floor is the most vulnerable area. Gravity will ensure that all water heads downwards and if your wet room floor has not been properly prepared and treated, you may have problems. Take a look at the diagram below and the text afterwards will explain how this type of wet room can be achieved with both a concrete floor and a timber floor. How to tank the walls and floor of a wetroom or shower room Wetroom Formed on a Concrete Floor The hardest thing about forming a wetroom floor when working on a concrete base such as a ground floor slab, is installing the drain pipe which takes the waste water away. ![]() Usually this is achieved by using a concrete breaker to dig a channel through the floor, with a large hole at the point where the waste outlet will sit. Using a concrete breaker to dig a drainage channel in a concrete floor The channel needs to go directly towards an outside wall to avoid digging up any other floors in other rooms. Once outside the building the drain can be laid to an existing manhole. The top of the new drain should be laid flush with the finished level of the concrete floor so any tanking can overlap the drain ensuring the water runs straight into the drain and cannot seep between the edge of the floor and the upstanding drain pipe. The pipe should also be trapped in the normal way to avoid foul gas running back into the wetroom. In a concrete floor it is usual to see a horizontal waste traps as shown in the image below Fitting a wet room floor grid, grill or floor plate Leading down, directly into the trap, sits the floor grid or outlet plate. This sits on top of the tanking and directs the water into the trap while holding hairs and other debris for cleaning. Should any water seep under the grid, it will of course go directly into the trap. The pipe should also be trapped in the normal way to avoid foul gas running back into the wetroom. In a concrete floor it is usual to see a horizontal waste traps as shown in the image below. The drains should be and any alterations to existing drain runs or access chambers, manholes etc. Should be notified to the Building Control Department of your local council. Fitting a horizontal waste trap to a wet room floor The channel housing the drain is then concreted over and a fall is constructed into the floor by using a self levelling floor compound, thickened slightly with sharp sand. There is no need for a steep slope to the floor. Water will find its way to the lowest level at any angle of fall. A fall of 10mm over 2m is plenty. Some wet room installers use a thicker bed of adhesive under the floor tiles to create the fall on the floor. We do not suggest that is a good idea as it means that the adhesive is not of a uniform thickness. Any cement or adhesive compound which varies in thickness stands a good chance of cracking at the thinnest point. This could lead to movement in the floor which cannot end well! The floor plate (see above) is positioned so the pipe goes down into the trap. The tanking is applied over the plate as are the tiles. A grid (or sometimes a channel) is then fitted into the top of the floor plate. How to put a wetroom shower tray into a timber or wooden floor To put a wetroom into a room with a timber floor, it is first necessary to take up the existing floorboards. The lowest point of the floor needs to be chosen and then the joists around that low point need to be raised a little (the same amount of fall as with the concrete floor applies) using strips of timber caled firring pieces. If you measure these timbers, your local joinery shop will cut them for you. Making sure the joists are absolutely solid (strengthening timbers (called noggins) can be placed in-between the joists if necessary) the plywood (minimum 25mm thickness is recommended here) must be screwed down to the joists and noggins at a minimum of 300mm centres.
