Installation

Two Installation Methods
Choose by Application

Built-in bathtubs come in two types: undermount and drop-in. Choose based on renovation budget and aesthetic goals

01 · Recommended

Under-mount Installation

The bathtub is set below the bathroom countertop, with the same material used for both the tub and counter. The seam is nearly invisible. This is the optimal installation method for solid surface and Corian® materials. The overall visual result is the best — the standard choice for five-star hotel standard rooms.

Best visual unitySame-material counter & tubEasiest to cleanHotel engineering preferred

02 ·

Drop-in Installation

A tiled or stone platform surrounds the bathtub. More flexible construction, lower cost — a practical choice for retrofits and budget-sensitive projects. The trade-off is different materials at the counter joint, which requires periodic maintenance at the seam.

Built-in core advantage: Integrated with counter, minimal floor footprint. In hotel standard room limited space, you can arrange a more complete bathroom functional area — the optimal solution for standard room bathrooms.

Why Built-In is the
Top Choice for Hotel Standard Rooms?

The global hotel standard room bathroom average area is only 4-6㎡. Built-in bathtubs are the only reasonable solution to achieve complete bathing functionality in limited space.

📐
Maximum Space Efficiency
Integrated with the countertop — no extra floor space needed. Even a 4m² bathroom can accommodate a complete bathroom trio: tub, shower, and toilet.
🧹
Easiest to Clean
Counter and tub in one seamless piece — no hidden dirt traps. Cleaning area reduced by ~40% versus freestanding. Housekeeping efficiency measurably improved.
🎨
Best Visual Unity
Tub and counter in matching material with an invisible seam. The bathroom presents as a cohesive, premium space. Visual quality that guests notice and review positively.
🏨
Best Value for Hotel Batch Orders
Built-in bathtubs have high production standardization, which translates to better pricing for large batch orders. The preferred choice for chain hotel procurement programs.

FAQ

Built-In Bathtub Customization FAQ

Built-in is the recommended choice for hotel standard rooms. Standard room bathrooms are typically limited to 4–6m². Built-in integrates with the countertop, using no extra floor space — enabling a complete bathroom trio (tub, shower, toilet) in compact areas. Freestanding bathtubs deliver a stunning visual impact but require 360° clearance space. Better suited to larger luxury suites. For standard rooms and regular suites: built-in. For executive suites and luxury accommodations: freestanding.

Under-mount delivers a superior result: same-material seamless join, clean sight lines, no hidden dirt corners, easiest to clean. This is the engineering standard for five-star hotel projects. Drop-in has lower cost and more flexible construction — suitable for limited budgets or historic building retrofits. For new construction projects with adequate budget: we strongly recommend under-mount.

Absolutely yes — and this is our most recommended approach. Both solid surface and Corian® can achieve a seamless same-material join between the bathtub and countertop. Professionally treated seams are nearly invisible. The overall result is far superior to mixing different materials. We offer integrated bathtub + counter customization as a complete package, with better pricing for full set orders.

We operate a strict batch color control process: (1) Sample color boards are shipped for your approval before production; (2) Batch production uses spectrophotometer testing on every production run — deviation ΔE ≤ 1.5 before release; (3) Same-batch items are prioritized for concurrent production; (4) Color board comparison records are included with delivery documentation. This ensures hundreds of bathtubs with highly consistent color, meeting the uniformity requirements of chain hotel brand programs.

Under-mount installation requires: (1) a bathroom floor plan with the drain hole position and counter dimensions marked; (2) confirmation of countertop material (solid surface counter + solid surface bathtub gives the best result); (3) confirmation of counter clearance height (≥bathtub height + 20mm maintenance space); (4) water supply and drain pipe positions pre-set. We provide detailed installation drawings with every product — ready for direct use by your construction team.
