We’ve put together a guide on how to fit a freestanding bath, helping you to safely and accurately install your new stone bath. This guide also includes other points you need to consider whilst in the process, including what items you need to fit a bath, the people you may need, and the do’s and don'ts.
We are using the Picasso bath to demonstrate how to install our freestanding baths. Some baths may have small nuances which you can double check using the specific product installation guide that can be downloaded on the product page.

BEFORE INSTALLATION
Before installation, you should download the technical drawing for the bath you have purchased. You can find this on the product page of the bath you have purchased. This will show you the exact dimensions of the bath base, the bath void depth and the location of the bath waste fitting. Please keep in mind that installation does differ depending on whether the floor is wooden or concrete and you should always take measures to ensure that the floor is level before installing your bath. As a safety precaution before you begin installation, make sure that all water is switched off at the mains. You will need a plumber and at least four people to lift and place the bath into the home due to its weight.
EQUIPMENT NEEDED
- Spirit level.
- Tape measure.
- Screwdriver.
- Pencil.
- Electric Drill.
- 2x Timber Lengths (for lifting).
HOW LONG WILL IT TAKE?
You should give a timeframe of two days overall to fit a freestanding bath. The process may take less time however you should always prepare for any problems you may encounter on the way that could slow down the process. If this is your only washing space, it’s a good idea to make alternative arrangements in the time that your bath is being fitted.
FITTING YOUR FREESTANDING BATH
Each Lusso stone bath is supplied with a low-profile waste connector and flexible pipes that fit within the void area of the bath and the base of your floor. The end of this pipe measures 40mm. For installation purposes, the pipe pulls out and extends to a length of 850mm. Our bath waste pipes will work with all British Standard bath traps although we do recommend using a HEPVO waterless trap with an inline adapter. These can be purchased from all major plumber centres and DIY stores.

INSTALLING A FREESTANDING BATH ONTO A WOODEN SURFACE
Step 1 - Mark the footprint of the bath base on the floor and within the footprint, bring the waste pipe through the floor.
Step 2 - Once step one is carried out, you should finish your floor covering.
Step 3 - Place two lengths of timber at either end of the bath and lift the bath onto the timber so that it is propped up high enough to connect the waste fitting to your trap.
Step 4 - Once you have connected the waste pipe to your trap you need to check the bath for any leaks. To do this, you will need to fill the bath halfway and release the waste.
Step 5 - Once you are satisfied that there are no leaks, you will need to remove the timbers and lower the bath into position. Your bath is now installed.
INSTALLING A FREESTANDING BATH ONTO A CONCRETE SURFACE
Step 1 - Using a 44mm hole saw drill attachment you will need to drill a circular hole in the cavity wall at the base of the bath (the back of the bath). Please note that this does not void your warranty.
Step 2 - Mark the footprint of the bath base on the floor.
Step 3 - With the bath footprint, you need to bring your waste pipe across the floor behind the bath and through the hole you have drilled.
Step 4 - Place two lengths of timber at either end of the bath and lift the bath onto the timber so that it is propped up high enough to connect the waste fitting to your trap.
Step 5 - Once you have connected the waste pipe to your trap you will need to check the bath for any leaks. To do this, you will need to fill the bath halfway and release the click clack waste.
Step 6 - Once you are satisfied that there are no leaks you will need to remove the timber and lower the bath into position. Your bath is now installed.
DO'S AND DON'TS
- Create a checklist and ensure you have everything you need before beginning the process.
- Take care when removing the previous bath and get help from a plumber if the plumbing needs to be rerouted.
- Turn off the water supply before beginning any work.
- Measure out all markings before beginning work.
- Wear safety goggles when drilling.
- Get assistance with lifting and transporting the bath.
- Provide the correct aftercare for your bath.
- Don't over tighten the fixings as this can cause damage to the bath.
Our stone baths are significantly heavy, weighing between 110kg and 300kg, so it’s important to install them safely and accurately. With an array of shapes and designs, you’re stone bath will make a statement once installed.
