Have you considered Acrylic Solid Surface? Some products to consider are LivingStone, LG HiMac. Great colors, easy to clean and it looks very nice. You can have your fabricator install a caddy that can fit into the shower wall.

Any of the industry's standard laminates, whichever brand one chooses will provide a level of durability suitable for the "time being" per se. Wilsonart trades on having a thicker, more robust wear layer and more matte/gloss patterning to camouflage any wear to a higher degree. Mind you, the investment will be significantly more expensive. An exploration of the alternatives will reveal many newer edges out there for laminate, a departure from the more commonplace waterfall edge. However, if your situation is temporary, it might be most prudent to question whether an upgrade is necessary at all. Acquire the most palatably priced materials from your local merchant and DIY. High gloss finishes would be an interesting flourish, truly suited to vertical application. Gloss finishes wear dreadfully though, something one should keep in mind in a space as harshly corrosive as a shower can be.
