My wife got a large fountain for her birthday. She likes the sound of running water while she reads. What she doesn't like is damp carpet because the fountain splashes a little, as running water is wont to do. We had a choice of returning the fountain or me getting busy to build her a table for it.
The entire project is simply 2x4s and 2x6s. The top measures 44" x 36" and is made completely of pocket hole-joined 2x6s. The base is all made of 2x4s and is 16" high (plus top). I went for a little different look on the legs with a 15 degree cut, to a height of 4".
We both liked the look the Corona square table (the top especially)...BUT! She likes to be able to vacuum under furniture without having to move it or get Down on hands and knees with the wand attachment. So...recessed cross-brace to the rescue! I rigged up the miter saw to cut 1 1/2" into my bottom braces (2x4s on edge front-to-back), the exact depth of my cross piece (a 2x4 laid flat), and made repeated cuts, then leveled with a chisel.
I made sure to adequately brace the top, since the fountain, plus rocks, plus water comes in at well over 100 pounds. The pictures aren't all that great, but what can you expect when some are taken in an unfinished basement with no windows, on a cell phone...right?
You could probably replicate this for less than the $150 I spent, but I needed the wood, new stain, urethane, and new brushes.
3 coats Minwax spar urethane, lightly sanded between coats for water resistance
