Holiday cottages for Christmas and New Year

Every home on this page does, and each listing shows it in the photos and the facilities list. If you can't see it on a listing, it isn't one of these 21; ask us and we'll say which homes nearby have one.

Yes, for the fixed tubs: they are kept at temperature and ready when you walk in, usually around 38 to 40 degrees. The wood-fired tubs at Fferm Fach take an hour or two to heat from cold, which is part of the point. Fern Lodge's Lazy Spa is set up and heating before you get there.

No. On Anglesey the hot tub is included in the nightly price at every home on this page; there is nothing to book or pay for separately.

Private, at every home. Where two of our homes sit together, The Pines with The Cottage and The Coach House, and The Retreat with Cil y Gwynt and Llain y Brenin, each has its own tub; you never share with another party.

The controls, the jets and the lights are explained in the house guide, and the temperature is set before you arrive. If it shows an error or won't heat, message us on the number in the guide and we'll talk you through it or send someone. If a tub is out of action before your stay, you'll hear from us before you set off, and we'll offer a discount, a hired tub or a move.

Yes. The fixed tubs run all year, and winter is when they earn their keep; none of the Anglesey tubs is seasonal. Anglesey is windy from October to March, so the hot tub homes are the ones we'd pick for that half of the year.

All of ours: every Birch hot tub home on the island is pet friendly. Mor Awel takes up to two dogs, Seren at Fferm Fach and Tai Porth Llechog Lodge one each, and The Upperhouse asks you to agree it when you enquire. The tub is for people, not dogs.

Craig y Don's two tubs overlook the Menai Strait, Tan y Fron's eight-seater faces Red Wharf Bay, and Mor Awel's sits above Church Bay. The rest are in gardens or on terraces; each listing says.
