We are in the middle of a major master bath gut remodel. We removed a wall and total dimensions are about 10x11.5. Our initial contractor - who approved the materials and design closed up his shop after 14 years in business. We found a new contractor to do the job and have run into a few bumps. The current issue is the tile edging. The ‘pencil’ tile we ordered that coordinates with our 16x2.5 subway is actually outside corner trim. Our contractor recommended a white plastic edging that we aren’t crazy about. We bought this marble pencil that matches the shower pan and curb.

Which do you think would look better on the shower edge - pencil marble or plastic? The tile will be laid in a traditional subway pattern - not stacked like the image.

What about the niche? Which will be placed horizontally under the window. Should we use the plastic or marble? The edge around the curve will have the plastic because of the need for flexibility. Including picture of full wall that shower will be on. My drawings indicate d 24X24 tall linen cabinet and a window seat with two drawers to give you an idea of the design.

Our plan has always been to carry the subway tile across the entire area above the vanity and behind the toilet. Given our issue with edging, do you think we should carry it over the door as well? Sorry about my sad attempt to draw in our fixtures. 72 in vanity with 24X36 mirrors above each sink.

Anything else I should consider? Selecting a different tile for the walls is not an option and the collection only comes with the 'pencil' that really isn't a pencil.
