Mera SPA

Mera Spa sits inside the Sopot Marriott Resort & Spa, on the first floor at Bitwy pod Płowcami 59. It's built around nine treatment categories rather than a single signature service: body scrubs and wraps, facials, eye treatments, manicures and pedicures, therapy baths, and both solo and couples massages. Kids' services are also on the list, which fits the resort's family-friendly setup.

The water side of things is split between an adult-only infinity pool and a separate children's pool, plus a heated spa/wellness pool and a plunge pool for cooling off after treatments. A lifeguard is on duty, and towels are provided throughout. Outside the spa itself, the hotel's fitness center and a whirlpool are listed as on-site outlets as well.

A day pass is available, so this isn't strictly limited to overnight guests, though the booking page also flags it as hotel-guest accessible — worth confirming directly which arrangement applies when you call. Pricing sits in the upscale bracket for the region. Staff work in both English and Polish, and couples treatments are explicitly offered, making this a reasonable stop for two people wanting matching massages rather than separate solo bookings.

Opening hours run from 9am most days, closing at 9pm Tuesday through Saturday and at 8pm on Monday and Sunday. Given the resort setting on the Sopot beachfront, it works as a practical add-on to a day at the Baltic coast or a visit to the nearby pier, rather than a destination in its own right.
