Double-Walled Construction with Minimalist Detailing
The Antium59E freestanding tub features a double-walled acrylic construction with seamlessly bonded inner and outer shells, ensuring exceptional structural integrity and superior heat retention. To further enhance performance, we apply dense foam insulation to the inside cavity walls, which not only helps maintain water temperature but also gives the bathtub a more substantial, solid feel under hand and foot while reducing ambient noise. Its slim deck profile preserves a sleek, minimalist appearance and is designed for use with either a wall-mounted or freestanding tub filler.
Attaching the Tub to the Floor
It is very important to attach any freestanding bathtub to the floor. Our tubs are designed to accommodate industrial-strength Velcro pads, which attach securely to the six floor leveling feet. This feature ensures the tub remains firmly in place, preventing accidental movement during use. By stabilizing the installation, the Velcro pads protect not only the drain connection but also the overall integrity and long-term performance of the tub.
Flexible Drain Configuration
The end drain can be positioned on either the left or right side during installation. Ample clearance beneath the inner shell allows for an offset drain connection—ideal for avoiding costly floor plumbing relocation. In compliance with Universal Plumbing Code, a horizontal - hard pipe - drain diversion of up to 30 inches is permitted.
