hi there thanks for the update. The one flaw in this beautiful bathroom? There's always one thing! Thank you for letting me know about this detail, because I was seriously thinking of doing it this way myself. In terms of your bathroom, I wonder if a very neat bead of silicone on the top only - of the join between the glass and the vanity - could help? This way the underneath is still fee to breathe and not gather gunk. But I guess then you don't get that lovely clean glass feeling from inside the shower.....

Anything is possible if you really want it, however every solution has a cost and without knowing you full circumstance its hard to tell. So heres a few examples of typical fixes to discuss with your designer: With the right 'scabble' (breaking of concrete) you can create a setdown deep enough to 'screed' (thin layer of concrete applied to the new void) to get the falls required for a kerbless shower but this will depend on the current total cover of concrete (if you break out too much it can compromise the structure). If your home is on a 'joist and bearer system' (timber or steel frame) you could 'comp up' (increase the strength) of the supporting 'members' (frame structure) to reduce their depth which will give you a lowered floor area, then a 'topping compound' (similar to screed) could be applied to the new set down to create the falls. Likewise changing the placement of the joists from 'stacked' to 'inline' could provide the same outcome without the need of comping up. We manage teams of consultants (architects, engineers, etc) and builders every day on projects in the interest of our Clients and find it pretty common theres a single solution focus. Remember you have engaged them to design your dream not the other way around! Always get what you pay for.

My walk in was well over a metre deep and width was a couple of metres to the wall. The glass screen was a metre and a bit so there was no splashing into the room. The shower came off the end wall same as the pic however it was one of those variable height showers on a rod, I have no doubt the shower in the pic will be splashing into the room which would drive me nuts. Mine looked great, so open, neat, big, except the floor hadn't been layed properly so instead of the water going toward the drain under the shower head it went all over the bathroom, nearly 3 metres out right down to the loo creating a massive puddle in front of the vanity as well. Getting it sorted with the builder was nightmare I eventually gave up and ended up having a low barrier installed from glass to wall. It still looked fine and stopped the problem but one really has to ensure the floor angle is done properly before embarking on the walk-in shower exercise.

looks wrong as it is currently - IMO it would look way better centred in height between ceiling and vanity and also possibly better centred to the basin, since it's offset to the vanity - a mirror centred to the vanity but offset to the basin could look odd - but it's hard to judge accurately from those photos as it's hard to gauge the scale of all the various elements.............like with everything to do with design it's always about balance
