Walk in shower enclosures can be quite deceptive objects, providing a certain amount of leeway in their pricing and design only to trick you into buying something that was far from worth the exorbitant price you paid. This is not to imply any sort of malevolent impulse on the part of the manufacturers; nor am I implying that, in fact, a walk in shower has its own mind and is engaged in diabolic trickery in order to obtain your cash. Yet the fact remains that you should be a very conscientious buyer if you wish to avoid the traditional pitfalls into which a buyer of showers commonly falls.
Of course this is not a problem unique to walk in shower enclosures. Almost any device that is subject to your purchase may well have a value well above or well below its selling price; hence on some occasions you may achieve a bargain whilst on other occasions you will be, as they say, “shafted”. The goal therefore is to avoid the deviltry and achieve more bargains than shaftings so as to maximize your benefit. If you are maximizing your benefit then as a corollary you are also minimizing your loss, and vice versa.
You have to constantly keep an eye out for sinister but unconscious attempts to deprive you of your hard-earned spending money. A shower that has surprisingly few features for a high price tag is obviously such an attempt. Conversely a shower that costs the same as the previous example but with multiple functionality features would be a good deal regardless of the cost, because it is relatively much better than the other shower for the same price. Relativity counts for a lot when it comes to this arena.
Therefore it would be best if you were to practice and train in learning to spot such trickery. The main problem of course is the fact that the only way to really practice and train is in acquiring practical experience, which can only be acquired in the actual field. So you will have to stomach some losses initially before you can really start saving.
