A three wall alcove bath will only need one long side panel, which is called a front panel. For other configurations you will also need at least one short end panel. Corner baths can be a challenge to fit, and may need manufacturer-specific or custom-made bath panels.
Materials You Need to Consider
Bath enclosures can be made of almost anything, and in very high end custom bathrooms you may find stone, tile, or wooden panels encasing a bath. The vast majority of bath panels on the market, however, are made of either acrylic or MDF.
Acrylic: bath panels are affordable, come in a huge range of sizes and colours, and are very easy to install. Not all acrylic bath panels are alike: lower quality acrylic is more bendable and flexible, and may be more prone to discolouration or splitting over time, so keep that in mind.
MDF, or medium-density fibreboard, is another very popular material for bath panels. MDF comes in a wide variety of thicknesses: thicker panels are less likely to bend and will give a more solid-looking finish. Be sure that any MDF panels are properly treated for water resistance. Vinyl wrapped panels have been coated with a thin layer of plastic to seal them from moisture. MDF panels are usually installed over a frame for extra support.
