You should have minimum 5 ft but 6 ft is ideal. I've played pool where tables are 4 ft from the wall and it is too close. The standard pool cue length is 57" and the draw length is about 6" so 5 to 6 ft would be ideal.

Carpets would be the preferred choice over tiles.

New Zealand! You live in paradise! Porch paint is specially made paint for wooden porches or decks. Its not a stain but an actual hard wearing & weather resistant paint that allows the wood texture to show through. Its safe for indoor or outdoor use. It is self priming & self sealing. I have used porch paint for wood paneling & kitchen cabinets & when remodeling a staircase formerly covered with carpet. It comes oil based or water based acrylic. I prefer oil based for a glossy easy to clean finish for a wooden table top. You may check your local home improvement/hardware store or paint store. I use Glidden Porch Paint. Takes me only 2 coats for white & the oil based goes on easily with a roller. Dries quickly too. Good luck!
