It seemed important to you about the choice of the trap after you have explained the different ways to prepare for leaks.
There are two main trends: the siphons (round or square) and gutters. I'll show you a fairly simple advantages and disadvantages of each.
I think, as a first step is to choose a material resistant to different abrasives that could be used in showers, but also a durable material with limestone, I tend to opt for stainless steel, c ' is pretty simple, highly resistant to various products, limestone and in a manner general, resistant in time.
- traps
whether round or square, small or medium size, the main advantage of these traps is that you can put in new or under renovation, due to different heights that can be find (from 30mm high), its cost is also quite reasonable (it takes about 60 € for a steel trap, and about 90 € with dome sealing). there are traps with dome ring: the great advantage of these models is that the dome provides extra security against risks associated with water and can also be supported for installation of tiles, so it's a good support. I therefore recommend this type of model. you can find them in stores selling professional tile or tile on the site-a-domicile.com at the following address http://www.carrelage-a-domicile.com/virtuemart-180.html
- gutters
I would say the major trend of the moment, only downside: its price, it is still very expensive at the moment, it takes about 350 € for a stainless steel gutter.
very clean, the gutter goes very well with all kinds of tiles, however, it is rather reserved for walk-in showers of larger sizes, because the minimum size the gutter 1m long.
can be positioned at the beginning of the shower or at the bottom of the shower. if it is positioned at the entrance to the shower, it helps to be sure water does not spill all over your bathroom when the slope is too low. If it is positioned at the bottom of the shower, I recommend a model with recovery sealing wall is more reassuring and AC prevents water seepage.
