Fit the versatile tap adapters to the bottom of both faucets making use of 2 nuts as well as olives (often provided with the tub). Fit the plug-hole outlet by smearing mastic filler round the sink electrical outlet hole, and after that pass the electrical outlet with the hole in the bathroom. Use the nut supplied by the producer to fit the plug-hole. Check out the plug-hole outlet for an inlet on the side for the overflow pipe.
Next off, fit completion of the flexible overflow pipe to the overflow electrical outlet. Afterwards, screw the pipe to the overflow face which ought to be fitted inside the bath. Make certain you make use of all of the provided washing machines.
Attach the catch to the bottom of the waste electrical outlet on the bathtub by winding the thread of the waste outlet with silicone mastic or PTFE tape, and screw on the trap to the outlet. Connect all-time low of the overflow tube in a comparable manner.The bath must now be ready to be suited its last position.



Removing Old Touches


If you require to replace old faucets with brand-new ones as a part of your installment, then the first thing you must do is separate the water. After doing so, turn on the faucets to drain pipes any type of water remaining in the system. The procedure of getting rid of the existing taps can be quite bothersome because of the restricted access that is frequently the instance.
Utilize a basin wrench (crowsfoot spanner) or a faucet tool to reverse the nut that connects the supply pipelines to the taps. Have a towel all set for the remaining water that will certainly come from the pipelines. As soon as the supply pipes have actually been removed, use the very same device to loosen the nut that holds the taps onto the bath/basin. You will certainly need to stop the solitary faucets from turning throughout this procedure. Once the faucets have actually been removed, the holes in the bath/basin will need to be cleansed of any old sealing substance.
Prior to moving on to fit the new faucets, contrast the pipeline links on the old taps to the new taps. If the old taps are longer than the new taps, after that a shank adapter is needed for the new faucets to fit.

To mount faucets, fit the bottom of the outermost adaptable faucet port to the appropriate supply pipeline by making a compression join; after that do the exact same for the other faucet.
Switch on the supply of water and inspect all joints and brand-new pipework for leaks and also tighten them if required. Fill up the bathtub and also inspect the overflow electrical outlet and the typical electrical outlet for leaks.
Lastly, deal with the bath paneling as described in the maker's instruction manual. Tiling as well as securing around the bath tub should wait until the tub has actually been made use of at the very least when as this will settle it right into its final placement.



Fitting New Taps

If you need to fit a monobloc, then you will certainly call for minimizing couplers, which links the 10mm pipe of the monobloc to the conventional 15mm supply pipeline.
Next off, position the faucet in the installing hole in the bath/basin ensuring that the washing machines remain in place in between the faucet as well as the sink. Secure the faucet in place with the manufacturer given backnut. When the faucet is firmly in place, the supply pipelines can be attached to the tails of the taps.

The previous kind ought to be attached to the faucet finishes first, tightening up just by hand. The supply pipes can later on be attached to the other end. Tighten both ends with a spanner after both ends have actually been connected.



Tiling Around the Bath tub


In the area where the bath satisfies the floor tile, it is necessary to seal the joins with a silicone rubber caulking. This is necessary as the fitting can move enough to fracture an inflexible seal, causing the water to penetrate the wall surface in between the bathroom and the tiling, causing problems with dampness and feasible leaks to the ceiling below.
You can choose from a range of coloured sealers to assimilate your fixtures and installations. They are offered in tubes as well as cartridges, and can securing gaps up to a size of 3mm (1/8 inch).

The sealer can break rather early if you do not take into account this motion before securing.
Alternatively, ceramic coving or quadrant ceramic tiles can be used to edge the bathroom or shower tray.

How to Install or Replace a Bathtub


Find Your Dimensions


The first step in any bathtub installation or replacement is to select the right size tub for your bathroom. Start by measuring your existing bathtub’s alcove from wall to wall. The standard size for bathtubs is around 5 feet long and 30 or 32 inches wide. Purchase the size that’s closest to your previous tub.



 

After you’ve measured, you’ll need to figure out what type of tub you need. Face the alcove. If the drain is on the right-hand side, you’ll need a right drain tub. If it’s on the left, get a left drain tub. Easy enough, right?


Disconnect the Water Supply and Drain Assembly


Before you can start on your removal, make sure that you turn off the tub’s water supply. Some bathrooms have a shutoff valve, but if you don’t see one, you’ll need to turn off the supply at your house’s water main. Once the water’s off, open the valves to release any remaining air in the supply lines.



 

Then, disconnect the tub drain flange. This process varies based on the type of drain you have, but in most cases, you’ll need a drain flange removal tool to perform this task. If you’re feeling handy, you might be able to use a pair of needle-nose pliers to twist and pull the flange.



 

Now comes the fun part. In order to disconnect the drain assembly, you’ll need to be able to get to the space underneath the tub. You might need to access the tub drain from a crawlspace or a basement. Don’t forget to take a pipe wrench with you, as you’ll need it to loosen the pipe at the connection.


Cut Out the Old Tub


After removing the drainpipe assembly, you can take out the old bathtub. Cut a strip above the tub edge in the wall surrounding the bathtub that's about 6 inches in height. The tools you need here may vary depending on the type of wall surround you have in the alcove. If you’re cutting drywall, use a drywall saw and remove the section of the wall all the way down to the studs. If you have tile, you’ll need to use a grinder with a diamond blade to cut through the grout line. Then, use a chisel to remove the individual tiles. Take care here not to cut through any studs.



 

Find the tub flange. Remove the screws that attach the flange to the studs in the wall. At this point, the tub should be freed from the wall.



 

Once you’ve removed the flange, use a utility knife to cut away the caulk between the tub and the floor. When this is done, you should be able to lift the tub up and out of the alcove. Keep in mind that, depending on what it’s made of, the old tub could be tremendously heavy. You should plan to have a friend help you move it just in case.


Install the New Tub


Before you make any adjustments to the area, place the new tub in the alcove to make sure it fits properly and that the tub drain lines up with the P-trap underneath the floor.



 

Remove it and install a 2 x 4 ledger board. Measure the tub’s flange, then mark that height on the wall. Screw the ledger board to studs in the wall. This will help to support the weight of the tub.



 

Once the ledger board has been installed, go ahead and secure the drain to the tub. For this step, you’ll need some plumber’s putty. Roll a small amount of putty in your hands and wrap it around the underside of the drain flange. Push the drain into the tub from underneath the tub.



 

When the drain has been attached, connect the overflow drain. To do this, you’ll place the gasket on the overflow elbow and move it behind the tub. Once that’s on, connect the overflow pipe and the drainpipe, but take care not to overtighten.


Secure the Tub


After the connections are in, it’s time to set the tub in place. Before you start, make sure the flange lines up with the markings you made in Step 4. Because the ledger board holds the tub in place, it’s important that it matches up. If not, you’ll need to remove it and readjust.



 

Once your measurements line up, attach the flange to the studs on all three sides of the wall. Please note that you should not screw the flange to the wall. Instead, you should use roofing nails because they won’t rust over time. When the tub is in place, install the baseboard and the molding in front of and around the tub.



 

Repair and finish off the drywall or tile that you cut in Step 3. If you’re installing a fiberglass bath surround, now’s the time to adhere it to the alcove.



 

Then, enjoy your tub! While all these steps might seem intimidating, removing and installing a new bathtub is a relatively easy DIY project that can be completed in a single day. And now, when you settle in for your next bubbly soak, you can enjoy your bath without the distraction of a tub in disrepair.
