How to choose the right one
-
Check alcove drainage side
Alcove tubs require precise planning for plumbing. The Mariposa right-drain model fits standard setups where the drain is on the right. If your bathroom layout places pipes on the left, you need the left-drain version. This 179-pound tub is designed for single users in tighter spaces. Matching the drain side to your existing plumbing prevents costly modifications during installation. Verify your wall configuration before buying.
-
Measure width for drop-ins
Drop-in tubs often offer more width than alcove models. The Underscore black drop-in measures 44.4 inches wide, providing a wider soaking area. This extra space suits those who want a modern, bold look in a spacious bathroom. The Archer model is slightly narrower at 38.9 inches but remains deep. Ensure your deck cutout can accommodate the specific width of your chosen model to avoid fitment issues.
-
Assess floor weight capacity
Heavier tubs demand stronger floor support. The Mariposa left-drain model weighs 179 pounds, while the Archer weighs 160 pounds. The Underscore is lighter at 110 pounds. Consider the empty weight of the tub when evaluating your bathroom floor structure. Heavier units may require additional reinforcement, especially in upper-level bathrooms. Check your home’s construction standards to ensure it can safely support the chosen tub’s mass.
-
Verify length constraints
Despite being labeled 72-inch models, actual lengths vary. The Mariposa and Underscore both measure approximately 74 inches long. The Archer extends to 74.9 inches. These slight differences matter in tight alcoves or custom decks. Measure your available space carefully to ensure the tub fits without protruding. Accurate measurements prevent installation delays and ensure the tub aligns correctly with surrounding walls or countertops.
-
Select color for aesthetics
Color impacts the overall bathroom design. The Mariposa and Archer are white, offering a classic look that pairs with most decor. The Underscore is black, providing a striking contrast for modern interiors. Choose white for versatility or black for a bold statement. Ensure the color complements your tiles and fixtures. The material finish also affects maintenance, with black surfaces potentially showing water spots differently than white ones.
Frequently asked questions
What is the difference between the Mariposa right-drain and left-drain models?
The primary difference is the drain location. The right-drain model, model 1259-RA-0, places the plumbing on the right side. The left-drain version, model 1259-LA-0, shifts the drain to the left. Both share the same 38-inch width and 23-inch height. Choose based on where your bathroom pipes are located.
How much does a Kohler 72-inch tub weigh?
Weight varies by model. The Mariposa left-drain acrylic tub weighs 179 pounds. The Archer drop-in tub is lighter at 160 pounds. The Underscore black drop-in model is the lightest at 110 pounds. Ensure your floor structure can support the specific weight of your chosen tub before installation.
