Short answer: yes, if you are already opening the floor. Curbless showers get asked for more than anything else we build, and there is a good reason for it. They look better, they are far easier to clean, and they are the single best thing you can do to a bathroom you intend to still be using in thirty years.
Why they are harder than they look
A flush entry is not a curb you leave off. The floor has to slope to the drain across the whole entry, which means the substrate under the tile has to be built to that slope before anything else happens. In a slab home that often means recessing the drain assembly. It is a decision made at the very beginning of the job or not at all.
Water going where you do not want it
The objection people raise is water on the bathroom floor. Done properly it is a non-issue: correct slope, a linear drain sized for the flow, and a glass panel positioned to stop the spray. Done badly it is exactly the problem people fear, which is why this is not the detail to hand to the cheapest bidder.
Ageing in place, without it looking like it
No threshold means no trip hazard and a wheelchair or a shower chair rolls straight in. None of that has to look clinical. A bench, a hand shower on a slide bar and a grab bar in a finish that matches the fixtures reads as a design choice, not a medical one.
The waterproofing matters more here
With no curb holding water back, the waterproofing system underneath is doing all the work. We build every one on a full Hydro Ban system and flood-test it before tile goes on. If a contractor cannot tell you what is under their tile, that is your answer.
