First of all, the supporting framework supplied with the bath needs to be fitted (if called for) according to the producer's instructions. Next, fit the taps or mixer to the tub. When fitting the tap block, it is essential to make sure that if the faucet comes with a plastic washing machine, it is fitted in between the bath as well as the taps. On a plastic bathroom, it is also reasonable to fit a supporting plate under the faucets device to avoid pressure on the bathtub.
Fit the versatile tap adapters to the bottom of the two faucets making use of 2 nuts and olives (occasionally supplied with the tub). Fit the plug-hole electrical outlet by smearing mastic filler round the sink outlet hole, and after that pass the electrical outlet via the hole in the bath. Make use of the nut provided by the supplier to fit the plug-hole. Check out the plug-hole outlet for an inlet on the side for the overflow pipeline.
Next, fit completion of the adaptable overflow pipeline to the overflow electrical outlet. After that, screw the pipe to the overflow face which need to be fitted inside the bath. Ensure you use every one of the supplied washers.
Link the trap to the bottom of the waste electrical outlet on the bathtub by winding the thread of the waste electrical outlet with silicone mastic or PTFE tape, as well as screw on the catch to the outlet. Link all-time low of the overflow tube in a comparable manner.The bathroom must now be ready to be suited its last placement.
Removing Old Taps
If you need to change old taps with new ones as a part of your installation, then the first thing you need to do is separate the water supply. After doing so, switch on the taps to drain pipes any type of water remaining in the system. The process of eliminating the existing taps can be fairly bothersome as a result of the restricted accessibility that is frequently the case.
Utilize a basin wrench (crowsfoot spanner) or a tap device to reverse the nut that connects the supply pipelines to the taps. Have a cloth ready for the remaining water that will originate from the pipelines. As soon as the supply pipes have been eliminated, utilize the very same device to loosen the nut that holds the taps onto the bath/basin. You will certainly require to stop the single faucets from transforming during this procedure. As soon as the faucets have actually been eliminated, the holes in the bath/basin will need to be cleaned of any kind of old sealing substance.
Prior to moving on to fit the new faucets, compare the pipe links on the old faucets to the brand-new faucets. If the old taps are longer than the brand-new faucets, after that a shank adapter is needed for the new faucets to fit.
Installing the Bath tub
Making use of both wood boards under its feet, position the tub in the required position. The wood boards are handy in evenly spreading out the weight of the bathtub over the location of the boards rather than concentrating all the weight onto 4 tiny points.
The following goal is to make sure that the bath tub is leveled all round. This can be achieved by checking the spirit level as well as changing the feet on the tub until the spirit level checks out level.
To set up faucets, fit all-time low of the furthest adaptable faucet port to the appropriate supply pipeline by making a compression join; after that do the very same for the other tap.
Turn on the water supply as well as examine all joints and brand-new pipework for leakages and tighten them if needed. Fill the tub as well as also check the overflow outlet and also the typical electrical outlet for leakages.
Ultimately, fix the bath paneling as defined in the supplier's instruction manual. Tiling and securing around the bathtub must wait until the bath tub has been made use of a minimum of once as this will settle it right into its last placement.
Fitting New Taps
If the tails of the brand-new taps are plastic, then you will need a plastic adapter to stop damage to the thread. One end of the adapter fits on the plastic tail of the faucet as well as the other end gives a connection to the existing supply pipelines.
If you need to fit a monobloc, after that you will call for minimizing couplers, which attaches the 10mm pipe of the monobloc to the basic 15mm supply pipe.
Next, place the faucet in the installing opening in the bath/basin guaranteeing that the washing machines are in location in between the faucet and the sink. Secure the tap in place with the supplier given backnut. As soon as the tap is safely in position, the supply pipelines can be linked to the tails of the faucets. The faucets can either be connected by utilizing corrugated copper piping or with normal tap ports. The former kind must be attached to the tap finishes initially, tightening up just by hand. The supply pipes can later be linked to the various other end. Tighten both ends with a spanner after both ends have actually been attached.
Tiling Around the Tub
In the location where the bath fulfills the ceramic tile, it is required to seal the accompanies a silicone rubber caulking. This is important as the fitting can move enough to split a stiff seal, causing the water to pass through the wall surface between the bath as well as the tiling, causing complications with moisture and feasible leaks to the ceiling below.
You can choose from a range of coloured sealers to blend in your fixtures and also fittings. They are offered in tubes as well as cartridges, and also are capable of securing gaps up to a size of 3mm (1/8 inch). If you have a bigger void to fill up, you can load it with twists of soaked paper or soft rope. Keep in mind to constantly load the bathtub with water before securing, to allow for the motion experienced when the tub is in use. The sealant can break relatively very early if you do not take into account this motion prior to securing.
Additionally, ceramic coving or quadrant floor tiles can be used to edge the bath or shower tray. Plastic strips of coving, which are easy to use and also cut to size, are also easily readily available on the market.

A Step-by-Step Guide to Installing a Bathtub
Is your bathtub looking a bit dated lately? Believe it or not, installing a new one is a project you can do yourself. Whether your bathtub is broken or doesn’t fit in with your current bathroom’s design, you can fix it without having to hire a contractor or paying labour costs.
But, beyond saving money, there are other benefits of installing your own bathtub. When you do this project yourself, you can customise every step of the process. You can also make sure the finished product looks exactly the way you want it to.
This DIY project is quite involved, but by doing some research, preparing your bathroom and using the right equipment, it is definitely one you can take on. This guide will help you understand the technical procedures behind installing a new bathtub.
Remove the Existing Bathtub
To remove the old bathtub, you will need to turn the water supply off before you start any work. After you turn the water off, there will likely still be some water left in your plumbing system, which you can remove by turning on a faucet below the level of the bathtub. Once the water stops running, you are ready to start working.
The easiest way to remove the tub is to remove the faucet, handles and other piping and then pull the tub out from the wall. If this doesn’t work in your situation, you will need to remove part of the wall, remove the piping and then slide the tub out.
Choose the Right Bathtub
The ideal way to replace your bathtub is to find one that has the exact dimensions and has the drain and faucet on the same side as your old one. This way, it will fit in the same place and you won’t have to change the piping system in your bathroom. Choose a tub that matches your home’s decor and fits with the style of the bathroom.
Install the Plumbing and Ledger Board
You can purchase a tub drain kit at a hardware store which will have all the pieces you will need for your new tub’s plumbing. Follow the instructions that came with the kit to install the plumbing in the new tub and then take measurements to make sure the plumbing in the tub will align with the plumbing in your bathroom. If it doesn’t, now is the time to make necessary adjustments.
Some bathtubs need a ledger board that is installed on the wall behind the tub to help support it. If your new bathtub requires one, the directions that came with it will tell you how high it should be installed. If your old bathtub had a ledger board, and it is still in good condition, you can adjust its height to match the new bathtub.
Install the Bathtub
When the plumbing and ledger board are ready, you can install the new bathtub. Carefully lower it into the space, being careful not to damage the tub, wall, plumbing or ledger board. Since bathtubs are very heavy and you will need to line the tub up exactly, it is wise to have someone help you with this step.
Once the tub is in place, it needs to be perfectly level, so use a bubble level instead of estimating how level the tub is. Put the level on the top edge of the tub, not the bottom on the inside, since many tubs are designed with a sloped bottom.
If the bathtub isn’t level, adjust the ledger board and shift the tub until it is. When it is level, use screws to attach the tub to the wall studs. Most bathtubs have pre-drilled holes in the upper flange, so use these but do not over tighten the screws.
Hook up the Plumbing
Now that the bathtub is installed, it needs to be attached to your plumbing system. First, install the shoe fitting under the tub and drain pipe, then the overflow pipe and then the drain flange. Your tub plumbing kit will include specific instructions on how to install these pieces.
Install the Bathtub Surround
A bathtub surround will protect the walls around the tub from water damage and can give your new bathtub a more finished look. To install one, make sure the wall is completely clean and dry so that the adhesive will be able to hold the surround securely. Then, measure the surround and mark the same dimensions on the wall above the tub.
Following the directions that came with the surround adhesive, apply it to the wall. Press the surround against the wall on top of the adhesive and then pull it away for about three minutes to activate the adhesive, then apply the surround again. Keep in mind that this is the most common way to use an adhesive, but you should check the instructions on the package for any special steps.
If there is any excessive adhesive around the sides of the surround, you can use mineral spirits to remove it. Then use masking tape to hold the surround panels in place until the adhesive is dry. Using silicone, seal all the cracks between the surround panels and the gap between the bottom of the panels and the top of the bathtub.
If you want to install tile above your bathtub, instead of a bathtub surround, the process will be very similar. But, you will need to measure and cut tiles and install each one individually, using tile spacers to make sure they are evenly spaced. You will then use grout to fill in the spaces between the tiles.
