How To Repair A Caravan Shower Tray

Is the washroom floor or shower trays in your motorhome damaged? Don’t be discouraged. As time passes, everything begins to show signs of wear and tear.

Although shower trays in caravans are normally made from a very tough resin a DIY shower tray crack repair is possible for most people.

Of course if something dramatic has happened then quite frankly a caravan show tray replacement may be simpler, but for small issues read on:

The most common cause for a shower tray replacement is a crack or chip in the surface, which weakens the tray and, over time, leads to loss of strength and an unexpected collapse.

If your caravan shower tray is cracked, there are a few things you can do to try and fix it:

Seal The Crack

Try using super glue or epoxy to fix the crack. This is the quickest and easiest option, but it might not be strong and could break again.

If the crack is small, you could try filling it with a waterproof sealant or silicone. This might not be very strong either, but it will help to stop any water from getting through.

Prepare The Surface

Lightly scuff the shower tray to fade the gloss sheen and apply a paint coating after any plastic sealant has been set and dried completely.

Any remnants of the plastic sealer will be removed with a fresh coat of paint. Multiple applications of good quality polyurethane paint should suffice to strengthen and preserve the tray from surface cracks.

Clean the surface thoroughly with a home detergent before properly rinsing and drying it completely before painting to ensure it is clear of dust and debris. Then, to give your paintwork a clean and smooth finish, place masking tape over the edges of the shower basin.

Apply The Paint

To give the shower basin an attractive and fresh look, coat it with textured or smooth anti-slip paint in an appropriate color. You can also use UVR paint with rubber granules for a non-slip finish, along with a sturdy design that will last for years.

Using a textured roller, ensure a uniform finish while the textured version is applied.

Using a mixer and nitrile gloves, vigorously whisk your Protectakote before pouring it into a roller tray. Apply the paint unidirectionally using a suitable roller paintbrush, ensuring an evenly thick covering on the basin.

Allow drying until it is no longer tacky to the touch. Apply a second and, if necessary, a third layer after the first one has dried, depending on how much your shower tray is used.

The roller or brush can be maintained functional between coatings if stored carefully using a plastic bag. However, a second refill is also recommended for the second coat.

– If the crack is bigger, you might have to replace the whole shower tray. This can be expensive and time-consuming, but it will be the only sure way to fix it.

Before you do anything, check that anyone who has access to the caravan is properly dressed for showering. If there are any bare feet or poorly protected legs, your immediate priority should be to protect them from any injuries!

Remember, if your caravan needs repair under it’s guarantee cover, make sure you use an approved workshop to avoid invalidating the guarantee.
