A shower enclosure will be a part of your bathroom for years to come and buying one will be an investment into your house. Therefore, before buying a shower enclosure it is important to take into consideration the following, to ensure your new shower cubicle will last the test of time.

General Shower Enclosure Checks

Size, Shape and Height
There are many shapes of shower enclosure: square, rectangle, oblong and quadrant enclosures. Don't make your bathroom feel like it is cramped, choose a shower enclosure which gives you the feeling of space inside while showering and one which gives your bathroom the sense of space.
Positioning
If your new shower enclosure can be installed where your old shower used to be then this will save a lot of preparatory work, hassle and money as the hot, cold and the waste water pipes will already be in the correct place making them easy to attach to your new shower cubicle.
Shower Enclosures: With or Without Tray?
It may be preferential to choose a shower enclosure that comes with a tray. Due to the fact that the tray has been designed specifically for the given shower enclosure it will fit properly and will have less chance of water leakage.
Tiling
The inside walls of the shower enclosure will need to be tiled. Therefore, plan ahead to what tiles you want and then tile the area before installing the shower cubicle.

Testing

Corrosion Testing - Have you ever seen chrome plating that has chipped or peeled off? It spoils the finish of your new showers. This is why it's important to buy quality if you want your shower enclosure to look good. Buy from a company who has done anti-corrosion salt tests on all of their metal fittings.
Door Rollers - Maybe not one of the things you think about when buying a shower enclosure, but the shower door rollers are very important for the longevity and quality feel of the shower enclosure. The door runners which Di Vapor uses for their shower enclosures have been tested for over 100,000 consecutive uses: that's a lot of showers!
Water Leakage - A good seal, often with magnetic strips on the shower doors is important to keep water inside the shower. Good seals also make the shower enclosure more aesthetically pleasing.
Door Handles and fixings - Door handles which are solid metal are much higher quality than their chrome plated plastic counterparts. These plastic handles are weaker and can give a cheaper feel to the shower enclosure.
Delivery and VAT - A shower enclosure may seem reasonably priced and of good quality, however it may not include delivery. Watch out for hidden extras like V.A.T and delivery. These extras can add a significant amount to the final buying price of your shower enclosure.
