Boasting uninterrupted views across the Firth of Clyde to the Isle of Arran, The Waterside Hotel & Spa has completed a £3 million development that significantly strengthens its position in Scotland’s coastal hospitality market.
Owned and operated by SimpsInns, the family-run hotel in West Kilbride has introduced a new sea-view spa and fully refurbished restaurant as part of a wider investment programme.
The project forms a key part of the group’s strategy to enhance its leisure offering across Ayrshire and capture growing demand for spa breaks and short coastal stays.
Si! Spa at The Waterside adds a dedicated wellness facility designed to maximise the hotel’s beachfront setting. The spa includes six treatment rooms, a four-person Rasul, indoor thermal facilities with steam room, experience showers and relaxation areas, and a hydro pool.
Outdoor features include a sauna with views across the Firth towards Ailsa Craig, experience showers, a cold drench bucket, fire pit seating area and direct beach access from the spa garden.
The spa works with ishga and ESPA, aligning the treatment menu with established premium brands. The offer is structured to appeal to both day visitors and overnight guests, broadening the hotel’s revenue streams beyond accommodation.
The hotel’s food and beverage operation has also been repositioned with the launch of Dunes Restaurant & Bar.
The redesigned space overlooks the hotel’s private gardens and the beach, and introduces a new menu developed by Group Executive Chef Ewan McAllister.
The menu focuses on Scottish produce, including West Coast mussels, Scottish king scallops, prime ribeye steaks and casual dining options such as smash burgers.
The development follows the recent completion of a 17-bedroom extension, increasing total room stock to 40. The new rooms include sea-facing options with Juliette balconies on the first floor and ground-floor bedrooms with private patios.
The Kilmory Suite forms the premium category within the extension, featuring a private balcony with hot tub, separate bedroom, living space and two bathrooms. The suite is designed to accommodate couples or small groups, providing flexibility within the hotel’s room mix.
The Waterside has an established reputation as a wedding venue, with the Kyle Suite refurbished at the end of 2025 to support continued growth in the events market. Its seafront location remains a key selling point for both ceremonies and leisure stays.
Jack Simpson of SimpsInns said, “This is a proud moment for the whole SimpsInns team. After years of planning and hard work, we’re thrilled to have opened the doors to Scotland’s ultimate new spa break and day spa destination.
“Our new sea-view spa development is now one of the most exciting leisure and tourism openings in Scotland for 2026.
“At SimpsInns, we’re committed to exceeding our guests’ expectations and are regularly investing in our hotel and leisure facilities. At The Waterside, we’re now able to provide even more space and amazing spa facilities for people to enjoy the iconic Ayrshire coast backdrop with its white sand beaches and views over the Firth of Clyde towards the Isle of Arran.”
The hotel’s overall approach emphasises integration between accommodation, wellness, dining and events, creating multiple revenue channels while leveraging its coastal location.
By combining spa and restaurant experiences with high-quality bedrooms and event spaces, The Waterside can attract both local and national visitors year-round.
This investment positions the property to compete effectively in the growing Scottish leisure market, responding to demand for experiential coastal breaks that combine convenience, service and a strong sense of place. With overnight rates from March 2026 starting at £115 per room, per night, based on two people sharing on a bed and breakfast basis, The Waterside Hotel & Spa is positioning itself as an accessible upscale coastal destination.
The combined investment in spa, restaurant and bedrooms reflects SimpsInns’ long-term strategy to strengthen its presence in the Ayrshire market and respond to sustained demand for experiential leisure breaks centred on location, wellness and food.
