Frequently Asked Questions
Everything you need to know before you dive in.
How do I find the right size for my Sink Swimwear?
We provide a comprehensive size guide on each product page. Our suits are designed with high-stretch Italian Lycra, but if you are between sizes, we generally recommend sizing up for the most comfortable fit.
What is your return policy?
We offer a 30-day return window for all unworn items. To be eligible for a refund, the hygiene liner must be intact and all original tags must be attached.
How should I care for my swimwear to make it last?
To maintain the vibrancy of the fabric, we recommend rinsing your swimwear in cold fresh water after every use. Hand wash with a mild detergent and lay flat in the shade to dry.
Do you ship internationally?
Yes, Sink Swimwear ships worldwide. International shipping times vary by location, typically taking 7-14 business days. Please note that customs duties may apply depending on your country.
Are your materials eco-friendly?
We are committed to sustainability. Our 'Deep Dive' collection is crafted using ECONYL® regenerated nylon, which is made from recycled fishing nets and ocean plastic waste.
When will my order be processed?
Orders are processed within 1-2 business days. Once your order has shipped, you will receive a confirmation email containing your tracking number.
