Case Study: Design and Construction of a 21-Meter-Long Transparent Acrylic Swimming Pool...

Title：21‑Meter Acrylic Infinity Pool at Hangzhou 5‑Star Hotel | Full Custom Build by Shanghai Qiankai Acrylic

Abstract

Featured at a luxury five‑star hotel in Hangzhou, this 21‑meter infinity swimming pool adopts 120 mm high‑transparency acrylic panels. Its transparent acrylic wall stretches 18 meters with a viewing height of 1.2 meters, delivering a stunning infinity visual effect. Shanghai Qiankai Acrylic delivered full‑turnkey EPC service including design development, acrylic panel manufacturing, hot‑bending forming, on‑site installation & commissioning. This article covers budget reference, technical challenges and the complete construction workflow for commercial hotel acrylic pool projects.

Body

This landmark infinity pool sits inside a premium five‑star hotel in Hangzhou. The overall pool length reaches 21 820 mm, while the transparent acrylic section extends 18 meters with 1.2 m viewing height. 120 mm‑thick hot‑bent acrylic forms smooth curved corners. Crystal‑clear acrylic reveals water ripples and ornate pool‑bottom patterns, erasing the physical boundary between water and hotel public space.

Different from conventional concrete pools, acrylic infinity pools highlight transparent viewing walls. Guests outside can view the whole water scene directly. The pool becomes a popular photo‑spot and greatly elevates the hotel’s premium brand experience.

Total project cost depends on acrylic thickness, dimension, hot‑bending curvature, site condition and scope of turn‑key service.

1. Acrylic panel: Thick custom hot‑bent acrylic takes the major cost share. This Hangzhou hotel case uses 120 mm curved acrylic for the 18‑meter transparent facade.
2. Auxiliary works: Steel‑structure reinforcement, waterproof sealing system, hydrostatic pressure calculation, special transportation, lifting, on‑site installation and after‑sales maintenance.

Note: Complete commercial hotel‑grade acrylic infinity pool normally starts at millions RMB. Final quotation requires drawing review, hydraulic parameter analysis and site survey. Shanghai Qiankai Acrylic offers free drawing optimization and customized quotation.

Warning: Thin low‑cost acrylic brings high risk of cracking and water leakage under water pressure. Commercial hotel projects must adopt swimming‑pool‑grade high‑thickness pure acrylic with professional structural verification for long‑term safe operation.

Complete Construction Process by Shanghai Qiankai Acrylic

Shanghai Qiankai Acrylic provided full‑chain EPC solution for this Hangzhou five‑star hotel infinity pool.

1. Design Deepening & Hydro‑structural Calculation Based on original hotel architectural drawings and water‑level elevation WL8.280, engineers calculated hydrostatic pressure, confirmed 120 mm panel thickness, optimized curved hot‑bending profile, and validated steel support & water‑stop groove structure to prevent leakage and deformation.
2. Custom Panel Production & Hot‑Bending Large‑size swimming‑pool‑grade acrylic blanks were produced and high‑gloss polished. Large‑form hot‑bending equipment shaped the large‑radius curved acrylic components, ensuring smooth surface free of bubbles and scratches.
3. Pre‑assembly Inspection In‑factory Pre‑assembly test was completed before delivery to check joint gaps and light transmission quality, eliminating potential defects before shipment.
4. Specialized Oversized‑cargo Transportation Fragile extra‑long acrylic units were well‑packaged and shipped by special heavy‑duty truck to the Hangzhou hotel site.
5. Lifting, Positioning & On‑site Sealing Installation Cooperating with civil‑engineering steel structure on‑site, crews lifted and positioned acrylic panels precisely. High‑precision water‑stop sealing and anti‑pressure reinforcement were finished for waterproof joints.
6. Water‑filling Commissioning, Leakage Test & Project Acceptance Gradual water filling and staged pressure‑holding leakage inspection were performed. After long‑duration pressure test with acceptable deformation data, the project was formally handed over, together with technical guidance for daily maintenance.

Project Value

Thanks to its 18‑meter long transparent acrylic facade, this 21‑meter hotel infinity pool turns into a core highlight of the property. Transparent acrylic breaks solid wall barriers and extends water landscape visually. It satisfies swimming function meanwhile acts as landscape artwork, upgrading atmosphere for hotel guest areas. Shanghai Qiankai Acrylic delivers one‑stop solution including independent panel R&D, design, hot‑bending processing and site construction. We customize acrylic swimming pools and large aquarium viewing windows for high‑end hotels, commercial complexes and cultural‑tourism projects across China.
