Hi, here are some potential ideas!... sounds like you have an exciting project! I cannot wait to see the sandstone sculptures and walkway you create. 1. straight pathway with stones [houzz=] 2. retangular pathway with stones [houzz=] 3. staggered pathway with stones [houzz=] 4. squared offline pathway with square walkway pads [houzz=] This is from and idea book I created on my page. See more in Landscape Ideas, my page.

This is a tough one without re-doing the floors. Could you call a tile store? Maybe they have some type of treatment to 'rough up' the tiles. Also, since you have elders in the home, grab bars placed in well thought out locations might be a good idea anyway, along with skid-free rugs.

You can use natural stone like marble for floor but do not use granite for floor at all as it is very slippery when wet. As for tiles do not go for glazed vitrified tiles for the floor for the same reason. ( floor becomes slippery once wet and may cause mishap) Go for ceramic anti skid tiles that are specially meant for bathroom floor. For wall tiles you can use whatever you like and then decide over the matching anti skid floor tile/ marble. Double charged vitrified tiles are usually used for flooring in rest of the house.

Bathroom floor tiles have their own specifications. If you go to a tile shop and ask for the same, you'll get it with all the required specs specially designed for bathrooms.
