Have you thought about using luxury vinyl plank flooring (LVP) on the ceiling? They make some pretty good looking material these days. It solves the moisture issue. You can find a color that you will like. It is pretty easy to install. You just need to use a construction adhesive. The Cabin Doctor

No matter what, you will have wood movement due to seasonal humidity changes and that gets coupled with temperature changes in the bathroom. Both of those will cause shrink/swell cycling in the wood, which must be accommodated or else the boards will distort, crack, and detach from your substrate. That movement occurs across the wood grain and negligibly along its length. The movement is uniform, meaning that for whatever material you use, it will have a certain of movement driven by changes in the temperature and or moisture content of the wood that gets applied to the whole stick of wood. It is best to think of that movement being applied to individual cubic millimeters of your wood and the movement is additive, so thicker wood will move more than thinner wood and ditto with the width.
Traditionally, T&G or shiplaps are used to camouflage this movement and help anchor both edges of the boards. You need to decide if you want concealed fasteners (hidden under the T&G or shiplap) or visible as a puttied face-nail installation. Face-nailing would be placed periodically down the centerline (lengthwise) of each board so that movement is balanced across the width. For sure, do not make the mistake of fastening more than the one single lengthwise run on each board or the expansion/contraction will fight the multiple lines of fastening.
You might consider using a pre-finished engineered wood flooring with T&G and micro-beveled edges. That way you get everything you want in a stable format.
