Much more than a sand and water table, it's an indoor/outdoor sensory center! There's a waterplay table with drain plug (holding 15 gallons of water), sand table (holding over 250 lbs. of sand), two removable tubs for holding both sand and water, storage table with a place to store the two tubs underneath (and don't need to be empty), with lids for table top use. There are four 4" diam. easy-glide, lockable wheels for mobility, smooth rounded edges, and earthtone colors. Use the lids with sand for an additional writing center or the table ledges for balances or tools.
