I popped into a tile shop to look for retro options for our kitchen and came out with info for the bathroom. This business still make soapdishes in Australia and two of them have spots for you toothbrushes too. They make them in nine colours -

I also thought I would scan this page from my retro engineering catalogue. This is what was put into homes around the 1950's in Australia.
