Aesthetically a level entry shower provides clean lines and the creation of space - as well as often giving design flexibility and a more open bathroom. Of course this isn't an advantage if you prefer the look of a Hob - see above.

Practically, level entry showers are a must for disabled or assisted showers. You may not require it now but it is a way you can future-proof your shower against even a temporary physical disruption. Despite every intention it is very hard to contain all of the water within the immediate confines of a level entry shower (creating a potential slip risk) so a hob is often chosen for that reason alone. Building and construction constrains may make level entry an expensive option so it is worthwhile checking first. If you can lower the shower floor area by 20mm then more often than not we will be able to accommodate a level entry shower.
