I did consider using a shower tray material from Home Despot but the tray material and glue were over $70 (Canuck bucks) with tax in. Yikes!Love the use of PVC to build stands but gotta ask ... where is the overflow tray for the sump? I had forgotten mine so I removed the sump tanks yesterday; built a small wall around the base; painted the wood; ran a PL400 bead over the cracks and put the tanks back in. I'll drill a hole in the stand; leave the pipe a couple of mm below the surface and plumb it to my drains next.
