<b>UNIQUE FEATURES</b><br> Our handcrafted free standing Japanese Ofuro style copper bath tubs with an integrated bench seat by Soluna feature a surface-mount installation. Designed for use with wall-mounted or floor-mounted bath tub faucets.<br><br>Soluna copper bathtubs come in four 'living' patina finishes: Matte Copper, Café Natural, Rio Grande and Dark Smoke. Follow the maintenance directions and tips below to keep that patina finish looking its absolute best.<br><br><b>Matte Copper</b> - raw hammered copper with a bright, shiny look of a newly minted penny. Not aged in the manufacturing process.<br><b>Café Natural</b> - an evenly colored surface that replicates the look of aged copper in a new sink. Color hues: brown sugar, milk chocolate, mocha and pumpkin pie.<br><b>Dark Smoke</b> - a dramatic finish that resembles oil rubbed bronze. Color hues: black, espresso, dark chocolate, sometimes with reddish highlights.<br><b>Rio Grande</b> - a unique finish created in a two-step process. First, Dark Smoke finish is applied. Then the patina is buffed from the ridges of the hammer marks, revealing the look of natural copper.<br><br><b>CLEANING AND MAINTENANCE TIPS</b><br>Note that 'living' patina finish will continue to evolve in look and color over time. Clean our hammered copper bath tubs with water and mild soap, and rinse them out after each use. Avoid soaps with citrus extracts as they may cause the copper patina to lighten. Do not use abrasive cleaners or harsh chemicals. Applying copper polish removes all patina, so it may only be used on tubs in Matte Copper finish.<br><br><b>DIMENSIONS</b><br><br>45" Diameter x 36" Height Outside*<br>39" Diameter x 31" Height Inside*<br>Integrated Seat Dimensions - 24" L x 12" W x 15" H<br>2" centered drain opening - for use with non-overflow tub drains<br>165 lbs approx. weight<br>158 gallons approx. water holding capacity<br><br>14 gauge Hammered Copper<br>TIG Copper Welded<br><br>*Dimensions may vary up to 3/8" +/-
