I tile my tubs surrounds with large format tile and use Fusion grout.

I did get the software from VMWare (Fusion), so that I could run XP on a virtual machine.

Paul,  have a sibling who works for large REITs and when I asked about the software question one name that came up was Fusion. 

Tile is the most durable floor and Fusion grout never stains or needs sealing and best if all, it is a consistant color because it is premixed so even a very dark grout has no efflourescence.

Nuclear fusion does generate energy, but always less than the amount of energy input into the reaction.

And that's happening all over the Bay Area as more and more millennials are finally swiping right on Tinder and matching with their soulmate :-P They shack up, sleep in the same bed, one thing leads to another and presto... you've got children.When that happens, baby momma wants a home to nest in, and doesn't care about being in the city core close to the hip Thai-Mexican fusion restaurant.

Eg. 1) Light switch on door jamb to turn on walk in closet light when door is opened. 2) I also always use Fusion grout...100% acrylic, never seal.I believe the lower price quadrant per property, the better return on bling.

When retiling tub surrounds I use fusion 100% acrylic grout because it shouldn’t stain, never needs sealing and has microban.
